CYV15G0101EQ  
Multi Rate Video Cable Equalizer  
Pb-free and RoHS compliant  
Features  
Uses Cypress CLEANLink™ technology  
Pin compatible to existing equalizer devices  
Multi rate adaptive equalization  
Operates from 143 to 1485 Mbps serial data rate  
SMPTE 292M, SMPTE 344M, and SMPTE 259M compliant  
Supports DVB-ASI at 270 Mbps  
Functional Description  
The CYV15G0101EQ is a multi rate adaptive equalizer designed  
to equalize and restore signals received over 75Ω coaxial cable.  
The equalizer meets SMPTE 292M, SMPTE 344M, and SMPTE  
259M data rates. The CYV15G0101EQ is optimized to equalize  
up to 350m of Belden 1694A coaxial cable at 270 Mbps and  
typically up to 200m of Belden 1694A coaxial cable at 1.485  
Gbps. The CYV15G0101EQ connects seamlessly to the  
HOTLink II family of transceivers.  
Cable length indicator for HD-SDI and SD-SDI data rates  
Maximum cable length adjustment for HD-SDI and SD-SDI  
data rates  
Carrier detect and mute functionality for HD-SDI and SD-SDI  
data rates  
Equalizer bypass mode  
The CYV15G0101EQ has DC restoration to compensate for the  
DC content of the SMPTE pathological patterns. A cable length  
indicator (CLI) provides an indication of the cable length being  
equalized at HD-SDI and SD-SDI data rates. The maximum  
cable length adjust (MCLADJ) sets the approximate maximum  
cable length to equalize at SD and HD data rates. The  
CYV15G0101EQ’s differential serial outputs (SDO, SDO) mute  
when the approximate cable length set by MCLADJ is reached.  
CD/MUTE is a bidirectional pin that provides an indication of the  
signal present at the equalizer inputs. It also controls muting the  
outputs of the equalizer at HD and SD data rates.

Output:  
When the incoming data stream is present and the cable length does not exceed that set by  
MCLADJ, the CD/MUTE outputs a voltage less than 0.8V.  
When the incoming data stream is not present or the cable length exceeds that set by  
MCLADJ, the CD/MUTE outputs a voltage greater than 2.8V.

Maximum Cable Length Adjust. The maximum equalized cable length is set by the voltage  
applied to the MCLADJ input. When the maximum cable length set by MCLADJ is reached,  
CD is driven high and the differential output is muted.  
If MCLADJ functionality is not needed, this pin should be left floating or tied to ground to  
allow maximum equalized cable length.  
MCLADJ works at both SD and HD data rates.  
Equalizer Bypass. When BYPASS is set HIGH, the signal presented at the equalizer’s  
differential serial inputs (SDI, SDI) is routed to the equalizer’s differential serial outputs  
(SDO, SDO) without performing equalization.  
When BYPASS is set LOW, the incoming video data stream is equalized and presented at  
the equalizer‘s serial differential outputs (SDO, SDO).  
In equalizer bypass mode, CD/MUTE is not functional.

CYV15G0101EQ  
Equalizer Operation  
MCLADJ  
The CYV15G0101EQ is a high speed adaptive cable equalizer  
designed to equalize standard definition (SD) and high definition  
(HD) serial digital interface (SDI) video data streams.  
CYV15G0101EQ equalizer is optimized to equalize up to 350m  
of Canare L-5CFB and Belden 1694A cable at 270 Mbps and  
typically up to 200m of Canare L-5CFB and Belden 1694A cable  
at 1.485 Gbps. The CYV15G0101EQ equalizer contains one  
power supply and typically consumes 160 mW power at 3.3V.  
The multi rate equalizer meets the SMPTE 259M, SMPTE 292M,  
SMPTE 344M, and DVB-ASI video standards. It meets all patho-  
logical requirements for SMPTE 292M as defined by RP198, and  
for SMPTE 259M as defined by RP178. The CYV15G0101EQ  
multi rate cable equalizer is auto adaptive from 143 Mbps to  
1.485 Gbps.  
Maximum Cable Length Adjust (MCLADJ) sets the approximate  
maximum amount of cable to be equalized. When the maximum  
cable length set by MCLADJ is reached, CD is driven high and  
the outputs are muted. MCLADJ works at SD and HD data rates.  
The graph in Figure 2 on page 7 illustrates the voltage required  
at MCLADJ input to equalize various Belden 1694A cable  
lengths for SD and HD data rates. If MCLADJ functionality is not  
needed, this pin should be left floating or tied to ground to allow  
maximum equalized cable length.  
CD/MUTE  
Carrier Detect/MUTE (CD/MUTE) is a bidirectional pin that  
provides an indication of the signal present at the equalizer’s  
input, or it controls the muting of the equalizer’s output. The  
(CD/MUTE) operates for both HD and SD data rates.  
The CYV15G0101EQ equalizer has variable gain and multiple  
equalization stages that reverse the effects of the cable. This  
equalization is achieved by separate regulation of the lower and  
higher frequency components in the signal to give a clean output  
eye diagram. The CYV15G0101EQ has DC restoration to  
compensate for the DC content of the SMPTE pathological  
patterns.  
If CD/MUTE is used as an output and the incoming data stream  
is not present or the cable length exceeds that set by MCLADJ,  
the voltage at the CD/MUTE output is greater than 2.8V. If  
CD/MUTE is used as an output, the incoming data stream is  
present and the cable length does not exceed that set by  
MCLADJ, then the voltage at the CD/MUTE output is less than  
0.8V.  
SDI, SDI  
If CD/MUTE is used as an input and is set LOW, the equalizer  
serial outputs are not muted. If the CD/MUTE is used as an input  
and is set HIGH, then the equalizer serial outputs are muted.  
The CYV15G0101EQ accepts single-ended or differential serial  
video data streams over 75Ω coaxial cable. It is recommended  
to AC couple the SDI and SDI inputs as they are internally biased  
to 1.2V.  
When an invalid signal or a signal transmitted with a launch  
amplitude of less than 500 mV at HD data rates is received, the  
equalizer’s serial outputs are muted.  
SDO, SDO  
The CYV15G0101EQ has differential serial output interface  
drivers that use current mode logic (CML) drivers to provide  
source matching for the transmission line. These outputs are  
either AC coupled or DC coupled to the HOTLink II SerDes  
device.  
BYPASS  
The CYV15G0101EQ has a bypass mode that allows the user to  
bypass the equalizer’s equalization and DC restoration  
functions. When the bypass mode is set HIGH, the signal  
presented at the equalizer’s differential serial inputs (SDI, SDI)  
is routed to the equalizer’s differential serial outputs (SDO, SDO)  
without equalizing.  
CLI  
Cable Length Indicator (CLI) is an analog output that gives an  
output voltage proportional to the equalized cable length. CLI  
gives an approximation of the length of cable at the differential  
serial inputs (SDI, SDI). CLI works at high definition (HD) data  
rates and standard definition (SD) data rates. The graph in  
Figure 3 on page 7 illustrates the CLI output voltage at various  
Belden 1694A cable lengths. With an increase in cable length,  
CLI output voltage decreases.  
When BYPASS is set LOW, the incoming video data stream is  
equalized and presented at the equalizer‘s differential serial  
outputs (SDO, SDO).  
In equalizer bypass mode, CD/MUTE is not functional.  
AGC  
Place a capacitor of 1 μF between the AGC± pins of the  
CYV15G0101EQ equalizer.

Power Up Requirements  
Maximum Ratings  
The CYV15G0101EQ contains one power supply. The voltage  
on any input or IO pin must not exceed the power pin during  
power up.  
Exceeding maximum ratings may shorten the useful life of the  
device. These user guidelines are not tested.
