CYV15G0104TRB
Independent Clock HOTLink II™ Serializer and
Reclocking Deserializer
transfer of data over a variety of high-speed serial links
including SMPTE 292M and SMPTE 259M video applications.
Features
®
• Second-generation HOTLink technology
• Compliant to SMPTE 292M and SMPTE 259M video
standards
• Single channel video serializer plus single channel
video reclocking deserializer
It supports signaling rates in the range of 195 to 1500 Mbps
per serial link. The transmit and receive channels are
independent and can operate simultaneously at different
rates. The transmit channel accepts 10-bit parallel characters
in an Input Register and converts them to serial data. The
receive channel accepts serial data and converts it to 10-bit
parallel characters and presents these characters to an Output
Register. The received serial data can also be reclocked and
retransmitted through the reclocker serial outputs. Figure 1
illustrates typical connections between independent video co-
processors and corresponding CYV15G0104TRB chips.
— 195- to 1500-Mbps serial data signaling rate
— Simultaneous operation at different signaling rates
• Supports reception of either 1.485 or 1.485/1.001 Gbps
data rate with the same training clock
• Internal phase-locked loops (PLLs) with no external
PLL components
• Supports half-rate and full-rate clocking
• Selectable differential PECL-compatible serial inputs
— Internal DC-restoration
The CYV15G0104TRB satisfies the SMPTE 259M and
SMPTE 292M compliance as per SMPTE EG34-1999 Patho-
logical Test Requirements.
As
a
second-generation
HOTLink
device,
the
CYV15G0104TRB extends the HOTLink family with enhanced
levels of integration and faster data rates, while maintaining
serial-link compatibility (data and BIST) with other HOTLink
devices. The transmit (TX) channel of the CYV15G0104TRB
HOTLink II device accepts scrambled 10-bit transmission
characters. These characters are serialized and output from
dual Positive ECL (PECL) compatible differential trans-
mission-line drivers at a bit-rate of either 10- or 20-times the
input reference clock for that channel.
• Redundant differential PECL-compatible serial outputs
— No external bias resistors required
— Internal source termination
— Signaling-rate controlled edge-rates
• Synchronous LVTTL parallel interface
• JTAG boundary scan
• Built-In Self-Test (BIST) for at-speed link testing
• Link Quality Indicator
The receive (RX) channel of the CYV15G0104TRB HOTLink
II device accepts a serial bit-stream from one of two selectable
PECL-compatible differential line receivers, and using a
completely integrated Clock and Data Recovery PLL, recovers
the timing information necessary for data reconstruction. The
recovered bit-stream is reclocked and retransmitted through
the reclocker serial outputs. Also, the recovered serial data is
deserialized and presented to the destination host system.
—Analog signal detect
—Digital signal detect
• Low-power 1.8W @ 3.3V typical
• Single 3.3V supply
• Thermally enhanced BGA
• Pb-Free package option available
• 0.25µ BiCMOS technology
The transmit and receive channels contain an independent
BIST pattern generator and checker, respectively. This BIST
hardware allows at-speed testing of the high-speed serial data
paths in each transmit and receive section, and across the
interconnecting links.

I/O Characteristics Signal Description
Transmit Path Data and Status Signals
TXDB[9:0]
TXERRB
LVTTL Input,
synchronous,
sampled by
TXCLKB↑ or
Transmit Data Inputs. TXDB[9:0] data inputs are captured on the rising edge of the
transmit interface clock. The transmit interface clock is selected by the TXCKSELB latch
via the device configuration interface.
[2]
REFCLKB↑
LVTTL Output,
Transmit Path Error. TXERRB is asserted HIGH to indicate detection of a transmit
Phase-Align Buffer underflow or overflow. If an underflow or overflow condition is
detected, TXERRB, is asserted HIGH and remains asserted until the transmit Phase-Align
Buffer is re-centered with the PABRSTB latch via the device configuration interface. When
TXBISTB = 0, the BIST progress is presented on the TXERRB output. The TXERRB
signal pulses HIGH for one transmit-character clock period to indicate a pass through the
synchronous to

or return of
TXERRB is also asserted HIGH, when any of the following conditions is true:
REFCLKB±
• The TXPLL is powered down. This occurs when TOE2B and TOE1B are both disabled
by setting TOE2B = 0 and TOE1B = 0.
• The absence of the REFCLKB± signal.
Transmit Path Clock Signals
REFCLKB±
Differential LVPECL Reference Clock. REFCLKB± clock inputs are used as the timing reference for the
or single-ended
transmit PLL. This input clock may also be selected to clock the transmit parallel interface.
When driven by a single-ended LVCMOS or LVTTL clock source, connect the clock source
to either the true or complement REFCLKB input, and leave the alternate REFCLKB input
open (floating). When driven by an LVPECL clock source, the clock must be a differential
clock, using both inputs.
LVTTL input clock
TXCLKB
LVTTL Clock Input,
internal pull-down
Transmit Path Input Clock. When configuration latch TXCKSELB = 0, the associated
TXCLKB input is selected as the character-rate input clock for the TXDB[9:0] input. In this
mode, the TXCLKB input must be frequency-coherent to its TXCLKOB output clock, but
may be offset in phase by any amount. Once initialized, TXCLKB is allowed to drift in
phase by as much as ±180 degrees. If the input phase of TXCLKB drifts beyond the
handling capacity of the Phase Align Buffer, TXERRB is asserted to indicate the loss of
data, and remains asserted until the Phase Align Buffer is initialized. The phase of
TXCLKB relative to REFCLKB± is initialized when the configuration latch PABRSTB is
written as 0. When TXERRB is deasserted, the Phase Align Buffer is initialized and input
characters are correctly captured.
TXCLKOB
LVTTL Output
Transmit Clock Output. TXCLKOB output clock is synthesized by the transmit PLL and
operates synchronous to the internal transmit character clock. TXCLKOB operates at
either the same frequency as REFCLKB± (TXRATEB = 0), or at twice the frequency of
REFCLKB± (TXRATEB = 1). The transmit clock outputs have no fixed phase relationship
to REFCLKB±.
Receive Path Data and Status Signals
RXDA[9:0]
LVTTL Output,
synchronous to the
RXCLKA ± output
Parallel Data Output. RXDA[9:0] parallel data outputs change relative to the receive
interface clock. If RXCLKA± is a full-rate clock, the RXCLKA± clock outputs are comple-
mentary clocks operating at the character rate. The RXDA[9:0] outputs for the associated
receive channels follow rising edge of RXCLKA+ or falling edge of RXCLKA–. If RXCLKA±
is a half-rate clock, the RXCLKA± clock outputs are complementary clocks operating at
half the character rate. The RXDA[9:0] outputs for the associated receive channels follow
both the falling and rising edges of the associated RXCLKA± clock outputs.
When BIST is enabled on the receive channel, the BIST status is presented on the
RXDA[1:0] and BISTSTA outputs. See Table 6 for each status reported by the BIST state
machine. Also, while BIST is enabled, the RXDA[9:2] outputs should be ignored.
Notes:
2. When REFCLKB± is configured for half-rate operation, these inputs are sampled relative to both the rising and falling edges of the associated REFCLKB±.
3. When REFCLKB± is configured for half-rate operation, this output is presented relative to both the rising and falling edges of the associated REFCLKB±.

BIST Status Output. When RXBISTA[1:0] = 10, BISTSTA (along with RXDA[1:0])
displays the status of the BIST reception. See Table 6 for the BIST status reported for
each combination of BISTSTA and RXDA[1:0].
When RXBISTA[1:0] ≠ 10, BISTSTA should be ignored.
REPDOA
Asynchronous to

Reclocker Powered Down Status Output. REPDOA is asserted HIGH, when the
reclocker output logic is powered down. This occurs when ROE2A and ROE1A are both
disabled by setting ROE2A = 0 and ROE1A = 0.

Receive Path Clock Signals
TRGCLKA± Differential LVPECL CDR PLL Training Clock. TRGCLKA± clock inputs are used as the reference source for
or single-ended
LVTTL input clock
the frequency detector (Range Controller) of the receive PLL to reduce PLL acquisition
time.
In the presence of valid serial data, the recovered clock output of the receive CDR PLL
(RXCLKA±) has no frequency or phase relationship with TRGCLKA±.
When driven by a single-ended LVCMOS or LVTTL clock source, connect the clock source
to either the true or complement TRGCLKA input, and leave the alternate TRGCLKA input
open (floating). When driven by an LVPECL clock source, the clock must be a differential
clock, using both inputs.
RXCLKA±
RECLKOA
LVTTL Output Clock Receive Clock Output. RXCLKA± is the receive interface clock used to control timing of
the RXDA[9:0] parallel outputs. These true and complement clocks are used to control
timing of data output transfers. These clocks are output continuously at either the half-
th
th
character rate (1/20 the serial bit-rate) or character rate (1/10 the serial bit-rate) of the
data being received, as selected by RXRATEA.
LVTTL Output
Reclocker Clock Output. RECLKOA output clock is synthesized by the reclocker output
PLL and operates synchronous to the internal recovered character clock. RECLKOA
operates at either the same frequency as RXCLKA± (RXRATEA = 0), or at twice the
frequency of RXCLKA± (RXRATEA = 1).The reclocker clock outputs have no fixed phase
relationship to RXCLKA±.
Device Control Signals
RESET
LVTTL Input,
asynchronous,
internal pull-up
Asynchronous Device Reset. RESET initializes all state machines, counters, and
configuration latches in the device to a known state. RESET must be asserted LOW for a
minimum pulse width. When the reset is removed, all state machines, counters and config-
uration latches are at an initial state. See Table 4 for the initialize values of the device
configuration latches.
LDTDEN
LVTTL Input,
internal pull-up
Level Detect Transition Density Enable. When LDTDEN is HIGH, the Signal Level
Detector, Range Controller, and Transition Density Detector are all enabled to determine
if the RXPLL tracks TRGCLKA± or the selected input serial data stream. If the Signal Level
Detector, Range Controller, or Transition Density Detector are out of their respective limits
while LDTDEN is HIGH, the RXPLL locks to TRGCLKA± until such a time they become
valid. SDASEL[2..1]A[1:0] is used to configure the trip level of the Signal Level Detector.
The Transition Density Detector limit is one transition in every 60 consecutive bits. When
LDTDEN is LOW, only the Range Controller is used to determine if the RXPLL tracks
TRGCLKA± or the selected input serial data stream. it is recommended to set LDTDEN
= HIGH.
ULCA
LVTTL Input,
internal pull-up
Use Local Clock. When ULCA is LOW, the RXPLL is forced to lock to TRGCLKA± instead
of the received serial data stream. While ULCA is LOW, the link fault indicator LFIA is
LOW indicating a link fault.
When ULCA is HIGH, the RXPLL performs Clock and Data Recovery functions on the
input data streams. This function is used in applications in which a stable RXCLKA± is
needed. In cases when there is an absence of valid data transitions for a long period of
time, or the high-gain differential serial inputs (INA±) are left floating, there may be brief
frequency excursions of the RXCLKA± outputs from TRGCLKA±.

Notes:
4. 3-Level Select inputs are used for static configuration. These are ternary inputs that make use of logic levels of LOW, MID, and HIGH. The LOW level is usually
implemented by direct connection to V (ground). The HIGH level is usually implemented by direct connection to V (power). The MID level is usually
SS
CC

CYV15G0104TRB HOTLink II Operation
CYV15G0104TRB Transmit Data Path
The CYV15G0104TRB is a highly configurable, independent
clocking device designed to support reliable transfer of large
quantities of digital video data, using high-speed serial links
from multiple sources to multiple destinations.
Input Register
The parallel input bus TXDB[9:0] can be clocked in using
TXCLKB (TXCKSELB = 0) or REFCLKB (TXCKSELB = 1).

CYV15G0104TRB
Phase-Align Buffer
Table 1. Operating Speed Settings
Data from the Input Register is passed to the Phase-Align
Buffer, when the TXDB[9:0] input register is clocked using
TXCLKBA (TXCKSELB = 0) or when REFCLKB is a half-rate
clock (TXCKSELB = 1 and TXRATEB = 1). When the
TXDB[9:0] input register is clocked using REFCLKB±
(TXCKSELA = 1) and REFCLKB± is a full-rate clock
(TXRATEB = 0), the associated Phase Alignment Buffer in the
transmit path is bypassed. These buffers are used to absorb
clock phase differences between the TXCLKB input clock and
the internal character clock for that channel.

Once initialized, TXCLKB is allowed to drift in phase as much
as ±180 degrees. If the input phase of TXCLKB drifts beyond
the handling capacity of the Phase Align Buffer, TXERRB is
asserted to indicate the loss of data, and remains asserted
until the Phase Align Buffer is initialized. The phase of
TXCLKB relative to its internal character rate clock is initialized
when the configuration latch PABRSTB is written as 0. When
the associated TXERRB is deasserted, the Phase Align Buffer
is initialized and input characters are correctly captured.
80–150
The REFCLKB± inputs are differential inputs with each input
internally biased to 1.4V. If the REFCLKB+ input is connected
to a TTL, LVTTL, or LVCMOS clock source, the input signal is
recognized when it passes through the internally biased
reference point. When driven by a single-ended TTL, LVTTL,
or LVCMOS clock source, connect the clock source to either
the true or complement REFCLKB input, and leave the
alternate REFCLKB input open (floating).
If the phase offset, between the initialized location of the input
clock and REFCLKB, exceeds the skew handling capabilities
of the Phase-Align Buffer, an error is reported on that
channel’s TXERRB output. This output indicates an error
continuously until the Phase-Align Buffer for that channel is
reset. While the error remains active, the transmitter for that
channel outputs a continuous “1001111000” character to
indicate to the remote receiver that an error condition is
present in the link.
When both the REFCLKB+ and REFCLKB– inputs are
connected, the clock source must be a differential clock. This
can either be a differential LVPECL clock that is DC-or
AC-coupled or a differential LVTTL or LVCMOS clock.
By connecting the REFCLKB– input to an external voltage
source, it is possible to adjust the reference point of the
REFCLKB+ input for alternate logic levels. When doing so, it
is necessary to ensure that the input differential crossing point
remains within the parametric range supported by the input.
Transmit BIST
The transmit channel contains an internal pattern generator
that can be used to validate both the link and device operation.
This generator is enabled by the TXBISTB latch via the device
configuration interface. When enabled, a register in the
transmit channel becomes a signature pattern generator by
logically converting to a Linear Feedback Shift Register
(LFSR). This LFSR generates a 511-character sequence. This
provides a predictable yet pseudo-random sequence that can
be matched to an identical LFSR in the attached Receiver(s).
Transmit Serial Output Drivers
The serial output interface drivers use differential Current
Mode Logic (CML) drivers to provide source-matched drivers
for 50Ω transmission lines. These drivers accept data from the
transmit shifter. These drivers have signal swings equivalent
to that of standard PECL drivers, and are capable of driving
AC-coupled optical modules or transmission lines.
Transmit Channels Enabled
A device reset (RESET sampled LOW) presets the BIST
Enable Latches to disable BIST on all channels.
Each driver can be enabled or disabled separately via the
device configuration interface.
All data present at the TXDB[9:0] inputs are ignored when
BIST is active on that channel.
When a driver is disabled via the configuration interface, it is
internally powered down to reduce device power. If both
transmit serial drivers are in this disabled state, the transmitter
internal logic for that channel is also powered down. A device
reset (RESET sampled LOW) disables all output drivers.
Transmit PLL Clock Multiplier
The Transmit PLL Clock Multiplier accepts a character-rate or
half-character-rate external clock at the REFCLKB± input, and
that clock is multiplied by 10 or 20 (as selected by TXRATEB)
to generate a bit-rate clock for use by the transmit shifter. It
also provides a character-rate clock used by the transmit
paths, and outputs this character rate clock as TXCLKOB.
Note. When the disabled transmit channel (i.e., both outputs
disabled) is re-enabled:
• the data on the transmit serial outputs may not meet all
timing specifications for up to 250 µs
• the state of the phase-align buffer cannot be guaranteed,
and a phase-align reset is required if the phase-align buffer
is used
The clock multiplier PLL can accept a REFCLKB± input
between 19.5 MHz and 150 MHz, however, this clock range is
limited by the operating mode of the CYV15G0104TRB clock
multiplier (TXRATEB) and by the level on the SPDSELB input.

[4]
SPDSELB is a 3-level select input that selects one of three
operating ranges for the serial data outputs of the transmit
channel. The operating serial signaling-rate and allowable
range of REFCLKB± frequencies are listed in Table 1.
Serial Line Receivers
Two differential Line Receivers, INA1± and INA2±, are
available on the receive channel for accepting serial data
streams. The active Serial Line Receiver is selected using the

Range Controls
The CDR circuit includes logic to monitor the frequency of the
PLL Voltage Controlled Oscillator (VCO) used to sample the
incoming data stream. This logic ensures that the VCO
operates at, or near the rate of the incoming data stream for
two primary cases:

> 100 mV, or 200 mV peak-to-peak differential.

Each Line Receiver can be DC- or AC-coupled to +3.3V
powered fiber-optic interface modules (any ECL/PECL family,
not limited to 100K PECL) or AC-coupled to +5V powered
optical modules. The common-mode tolerance of these line
receivers accommodates a wide range of signal termination
voltages. Each receiver provides internal DC-restoration, to
the center of the receiver’s common mode range, for AC-
coupled signals.

which it has been “missing.”
• when the incoming data stream is outside the acceptable
signaling rate range.
To perform this function, the frequency of the RXPLL VCO is
periodically compared to the frequency of the TRGCLKA±
input. If the VCO is running at a frequency beyond

periodically forced to the correct frequency (as defined by
TRGCLKA±, SPDSELA, and TRGRATEA) and then released
in an attempt to lock to the input data stream.
Each selected Line Receiver (i.e., that routed to the clock and
data recovery PLL) is simultaneously monitored for

During the time that the Range Control forces the RXPLL VCO
to track TRGCLKA±, the LFIA output is asserted LOW. After a

the LFIA (Link Fault Indicator) output associated with each

SDASELA latch sets the trip point for the detection of a valid
signal at one of three levels, as listed in Table 2. This control

performed by an integrated PLL that tracks the frequency of
the transitions in the incoming bit stream and aligns the phase
of the internal bit-rate clock to the transitions in the selected
serial data stream.
When a driver is disabled via the configuration interface, it is
internally powered down to reduce device power. If both
reclocker serial drivers are in this disabled state, the internal
reclocker logic is also powered down. The deserialization logic
and parallel outputs will remain enabled. A device reset
(RESET sampled LOW) disables all output drivers.
Each CDR accepts a character-rate (bit-rate ÷ 10) or half-
character-rate (bit-rate ÷ 20) training clock from the
TRGCLKA± input. This TRGCLKA± input is used to

outputs may not meet all timing specifications for up to 250 µs.

correct frequency (rather than a harmonic of the bit-rate)
• reduce PLL acquisition time
Output Bus
• limit unlocked frequency excursions of the CDR VCO when
there is no input data present at the selected Serial Line
Receiver.
The receive channel presents a 10-bit data signal (and a BIST
status signal when RXBISTA[1:0] = 10).
Regardless of the type of signal present, the CDR attempts to
recover a data stream from it. If the signaling rate of the
recovered data stream is outside the limits set by the range
control monitors, the CDR tracks TRGCLKA± instead of the
data stream. Once the CDR output (RXCLKA±) frequency
returns back close to the TRGCLKA± frequency, the CDR
input is switched back to the input data stream. If no data is
present at the selected line receiver, this switching behavior
may result in brief RXCLKA± frequency excursions from
TRGCLKA±. However, the validity of the input data stream is
Receive BIST Operation
The receiver channel contains an internal pattern checker that
can be used to validate both device and link operation. These
pattern checkers are enabled by the RXBISTA[1:0] latch via
the device configuration interface. When enabled, a register in
the receive channel becomes a signature pattern generator
and checker by logically converting to a Linear Feedback Shift
Register (LFSR). This LFSR generates a 511-character
sequence. This provides a predictable yet pseudo-random
sequence that can be matched to an identical LFSR in the
attached Transmitter(s). When synchronized with the received
data stream, the Receiver checks each character from the
deserializer with each character generated by the LFSR and
indicates compare errors and BIST status at the RXDA[1:0]
and BISTSTA bits of the Output Register.
indicated by the LFIA output. The frequency of TRGCLKA± is
[24]
required to be within ±1500ppm
of the frequency of the
clock that drives the REFCLKB± input of the remote trans-
mitter to ensure a lock to the incoming data stream. This large
ppm tolerance allows the CDR PLL to reliably receive a 1.485
or 1.485/1.001 Gbps SMPTE HD-SDI data stream with a
constant TRGCLK frequency.
The BIST status bus {BISTSTA, RXDA[0], RXDA[1]} indicates
010b or 100b for one character period per BIST loop to
indicate loop completion. This status can be used to check test
pattern progress.
For systems using multiple or redundant connections, the
LFIA output can be used to select an alternate data stream.
When an LFIA indication is detected, external logic can toggle
selection of the INA1± and INA2± input through the INSELA
input. When a port switch takes place, it is necessary for the
receive PLL for that channel to reacquire the new serial
stream.
The specific status reported by the BIST state machine is listed
in Table 6. These same codes are reported on the receive
status outputs.
If the number of invalid characters received ever exceeds the
number of valid characters by 16, the receive BIST state
machine aborts the compare operations and resets the LFSR
to look for the start of the BIST sequence again.
Reclocker
The receive channel performs a reclocker function on the
incoming serial data. To do this, the Clock and Data Recovery
PLL first recovers the clock from the data. The data is retimed
by the recovered clock and then passed to an output register.
Also, the recovered character clock from the receive PLL is
passed to the reclocker output PLL which generates the bit
clock that is used to clock the retimed data into the output
register. This data stream is then transmitted through the
differential serial outputs.
A device reset (RESET sampled LOW) presets the BIST
Enable Latches to disable BIST on all channels.
BIST Status State Machine
When a receive path is enabled to look for and compare the
received data stream with the BIST pattern, the {BISTSTA,
RXDA[1:0]} bits identify the present state of the BIST compare
operation.
Reclocker Serial Output Drivers
The BIST state machine has multiple states, as shown in
Figure 2 and Table 6. When the receive PLL detects an out-of-
lock condition, the BIST state is forced to the Start-of-BIST
state, regardless of the present state of the BIST state
machine. If the number of detected errors ever exceeds the
number of valid matches by greater than 16, the state machine
is forced to the WAIT_FOR_BIST state where it monitors the
receive path for the first character of the next BIST sequence.
The serial output interface drivers use differential Current
Mode Logic (CML) drivers to provide source-matched drivers
for 50Ω transmission lines. These drivers accept data from the
reclocker output register in the reclocker channel. These
drivers have signal swings equivalent to that of standard PECL
drivers, and are capable of driving AC-coupled optical
modules or transmission lines.

The transmit channel is controlled by the TOE1B and the

reclocker function is controlled by the ROE1A and the ROE2A

initialization value of the latches upon the assertion of RESET.
Table 5 shows how the latches are mapped in the device.
Each row in the Table 5 maps to a 7-bit latch bank. There are
6 such write-only latch banks. When WREN = 0, the logic value
in the DATA[6:0] is latched to the latch bank specified by the
values in ADDR[2:0]. The second column of Table 5 specifies
the channels associated with the corresponding latch bank.
For example, the first three latch banks (0,1 and 2) consist of
configuration bits for the reclocker channel A.
Latch Types
There are two types of latch banks: static (S) and dynamic (D).
Each channel is configured by 2 static and 1 dynamic latch
banks. The S type contain those settings that normally do not
change for a given application, whereas the D type controls
the settings that could change during the application's lifetime.
The first and second rows of each channel (address numbers
0, 1, 5, and 6) are the static control latches. The third row of
latches for each channel (address numbers 2 and 7) are the
dynamic control latches that are associated with enabling
dynamic functions within the device. Address numbers 3 and
4 are internal test registers.
Device Reset State
When the CYV15G0104TRB is reset by assertion of RESET,
all state machines, counters, and configuration latches in the
device are initialized to a reset state. See Table 4 for the
initialize values of the configuration latches.
Following a device reset, it is necessary to enable the transmit
and receive channels used for normal operation. This can be
done by sequencing the appropriate values on the device
[5]
configuration interface.
Static Latch Values
There are some latches in the table that have a static value
(i.e. 1, 0, or X). The latches that have a ‘1’ or ‘0’ must be
configured with their corresponding value each time that their
associated latch bank is configured. The latches that have an
‘X’ are don’t cares and can be configured with any value.
Device Configuration and Control Interface
The CYV15G0104TRB is highly configurable via the configu-
ration interface. The configuration interface allows the trans-
mitter and reclocker to be configured independently. Table 4
lists the configuration latches within the device including the

When RXRATEA = 1, the RXCLKA± clock outputs are complementary clocks that follow the recovered clock
operating at half the character rate. Data for the associated receive channels should be latched alternately on
the rising edge of RXCLKA+ and RXCLKA–.

TXCKSELB
TXRATEB
Transmit Clock Select. The initialization value of the TXCKSELB latch = 1. TXCKSELB selects the clock
source used to write data into the Transmit Input Register. When TXCKSELB = 1, the input register TXDB[9:0]
is clocked by REFCLKB↑. In this mode, the phase alignment buffer in the transmit path is bypassed. When
TXCKSELB = 0, TXCLKB↑ is used to clock in the input register TXDB[9:0].
Transmit PLL Clock Rate Select. The initialization value of the TXRATEB latch = 0. TXRATEB is used to
select the clock multiplier for the Transmit PLL. When TXRATEB = 0, the transmit PLL multiples the REFCLKB±
input by 10 to generate the serial bit-rate clock. When TXRATEB = 0, the TXCLKOB output clocks are full-rate
clocks and follow the frequency and duty cycle of the REFCLKB± input. When TXRATEB = 1, the Transmit
PLL multiplies the REFCLKB± input by 20 to generate the serial bit-rate clock. When TXRATEB = 1, the
TXCLKOB output clocks are twice the frequency rate of the REFCLKB± input. When TXCKSELB = 1 and
TXRATEB = 1, the Transmit Data Inputs are captured using both the rising and falling edges of REFCLKB.
TXRATEB = 1 and SPDSELB = LOW, is an invalid state and this combination is reserved.
TXBISTB
TOE2B
Transmit Bist Disable. The initialization value of the TXBISTB latch = 1. TXBISTB selects if the transmit BIST
is disabled or enabled. When TXBISTB = 1, the transmit BIST function is disabled. When TXBISTB = 0, the
transmit BIST function is enabled.
Secondary Differential Serial Data Output Driver Enable. The initialization value of the TOE2B latch = 0.
TOE2B selects if the TOUTB2± secondary differential output drivers are enabled or disabled. When TOE2B
= 1, the associated serial data output driver is enabled allowing data to be transmitted from the transmit shifter.
When TOE2B = 0, the associated serial data output driver is disabled. When a driver is disabled via the
configuration interface, it is internally powered down to reduce device power. If both serial drivers for a channel
are in this disabled state, the associated internal logic for that channel is also powered down. A device reset
(RESET sampled LOW) disables all output drivers.
TOE1B
Primary Differential Serial Data Output Driver Enable. The initialization value of the TOE1B latch = 0.
TOE1B selects if the TOUTB1± primary differential output drivers are enabled or disabled. When TOE1B = 1,
the associated serial data output driver is enabled allowing data to be transmitted from the transmit shifter.
When TOE1B = 0, the associated serial data output driver is disabled. When a driver is disabled via the
configuration interface, it is internally powered down to reduce device power. If both serial drivers for a channel
are in this disabled state, the associated internal logic for that channel is also powered down. A device reset
(RESET sampled LOW) disables all output drivers.
PABRSTB
Transmit Clock Phase Alignment Buffer Reset. The initialization value of the PABRSTB latch = 1. The
PABRSTB is used to re-center the Transmit Phase Align Buffer. When the configuration latch PABRSTB is
written as a 0, the phase of the TXCLKB input clock relative to REFCLKB+/- is initialized. PABRSTB is an
asynchronous input, but is sampled by each TXCLKB↑ to synchronize it to the internal clock domain.
PABRSTB is a self clearing latch. This eliminates the requirement of writing a 1 to complete the initialization
of the Phase Alignment Buffer.

Device Configuration Strategy
JTAG Support
The following is a series of ordered events needed to load the
configuration latches on a per channel basis:
The CYV15G0104TRB contains a JTAG port to allow system
level diagnosis of device interconnect. Of the available JTAG
modes, boundary scan, and bypass are supported. This
capability is present only on the LVTTL inputs and outputs, the
TRGCLKA± input, and the REFCLKB± clock input. The high-
speed serial inputs and outputs are not part of the JTAG test
chain.
1. Pulse RESET Low after device power-up. This operation
resets both channels.
2. Set the static latch banks for the target channel.
3. Set the dynamic bank of latches for the target channel.
Enable the Receive PLL and/or transmit channel. If the
receiver is enabled, set the device for SMPTE data
reception (RXBISTA[1:0] = 01) or BIST data reception
(RXBISTA[1:0] = 10).
3-Level Select Inputs
Each 3-Level select inputs reports as two bits in the scan
register. These bits report the LOW, MID, and HIGH state of
the associated input as 00, 10, and 11 respectively
4. Reset the Phase Alignment Buffer. [Optional if phase align
buffer is bypassed.]
JTAG ID
The JTAG device ID for the CYV15G0104TRB is ‘0C811069’x.

Notes:
8. Tested one output at a time, output shorted for less than one second, less than 10% duty cycle.
9. This is the minimum difference in voltage between the true and complement inputs required to ensure detection of a logic-1 or logic-0. A logic-1 exists when
the true (+) input is more positive than the complement (−) input. A logic-0 exists when the complement (−) input is more positive than true (+) input.
10. The common mode range defines the allowable range of REFCLKB+ and REFCLKB− when REFCLKB+ = REFCLKB−. This marks the zero-crossing between
the true and complement inputs as the signal switches between a logic-1 and a logic-0.

11. The common mode range defines the allowable range of INPUT+ and INPUT− when INPUT+ = INPUT−. This marks the zero-crossing between the true and
complement inputs as the signal switches between a logic-1 and a logic-0.
12. Maximum I is measured with V = MAX,T = 25°C, with all channels and Serial Line Drivers enabled, sending a continuous alternating 01 pattern, and

outputs unloaded.
13. Typical I is measured under similar conditions except with V = 3.3V, T = 25°C,with all channels enabled and one Serial Line Driver per channel sending

a continuous alternating 01 pattern. The redundant outputs on each channel are powered down and the parallel outputs are unloaded.
14. Cypress uses constant current (ATE) load configurations and forcing functions. This figure is for reference only.
15. The LVTTL switching threshold is 1.4V. All timing references are made relative to where the signal edges cross the threshold voltage.
16. Tested initially and after any design or process changes that may affect these parameters, but not 100% tested.

Notes:
17. The ratio of rise time to falling time must not vary by greater than 2:1.
18. For a given operating frequency, neither rise or fall specification can be greater than 20% of the clock-cycle period or the data sheet maximum time.
19. All transmit AC timing parameters measured with 1ns typical rise time and fall time.
20. Parallel data output specifications are only valid if all outputs are loaded with similar DC and AC loads.
21. Receiver UI (Unit Interval) is calculated as 1/(f
* 20) (when TRGRATEA = 1) or 1/(f
* 10) (when TRGRATEA = 0). In an operating link this is equivalent to t .

Notes:
23. The duty cycle specification is a simultaneous condition with the t
and t
parameters. This means that at faster character rates the TRGCLKA± duty
TRGL
TRGH
cycle cannot be as large as 30%–70%.
24. TRGCLKA± has no phase or frequency relationship with the recovered clock(s) and only acts as a centering reference to reduce clock synchronization time.
TRGCLKA± must be within ±1500 PPM (±0.15%) of the transmitter PLL reference (REFCLK±) frequency. Although transmitting to a HOTLink II receiver channel
necessitates the frequency difference between the transmitter and receiver reference clocks to be within ±1500-PPM, the stability of the crystal needs to be
within the limits specified by the appropriate standard when transmitting to a remote receiver that is compliant to that standard.
25. While sending BIST data at the corresponding data rate, after 10,000 histogram hits, time referenced to REFCLKB± input.
26. Receiver input stream is BIST data from the transmit channel. This data is reclocked and output to a wide-bandwidth digital sampling oscilloscope. The
measurement was recorded after 10,000 histogram hits, time referenced to REFCLKB± of the transmit channel.
