1.2.1 CDR loader (CDR main module CDL4009 or MAR770):  
This complete CDR loader is considered as not repairable in the field. therefore this module will be repaired centrally. A  
module exchange procedure will be set up for this purpose. The module can be removed from the product by removing 4  
screws and the transformer (see demounting the CDR module on page 1-7), and loosing the connectors.  
This module is the complete CD recorder, it contains the following parts:  
CD Mechanism (CDM4009'). Underneath this mechanism a PCB is mounted which is adjusted to the mechanism (laser  
current settings are stored in EEPROM).  
Loader Assy. This mechanical assy takes care for the tray control.  
Main PCB. This PCB takes care that the (analog or digital) signal to be recorded is converted into a suitable signal which  
can be recorded on the disc.  
Digital signals with an other sampling frequency then 44.1kHz will be converted in the sample rate converter (DASP) to  
44.1kHz.  
Analog signals will be first converted into a digital converter by the AD converter.  
This PCB also takes care that the signal from the CD (playback) is converted into a suitable digital signal (or analog via  
the DA converter).  
The main microprocessor controls the several functions of this PCB.  
1.2.2 Power Supply PCB.  
This PCB contains the Power SW, which is jointed the Power bottom on the front panel. This PCB consists of power supply  
part. The power suppluy part delivers the several voltages for the diffrent PCB in the DR6050. On this power supply one  
fuse (primary side) is mounted on this PCB. All parts are available as spare parts.  
1.2.3 Terminal PCB.  
This PCB coutaius input and output terminals. All parts are available as spare parts.  
1.2.4 Display Board.  
This PCB contains the Display, which informs the user about the status of the recording/playback process and it also takes  
care for scanning the keys on the front panel. The information from the keys is fed via a I2 C connection to the main  
microprocessor on the CDR loader module. Information which needs to be displayed is also fed via this I2 C line from the  
main microprocessor on the CDR loader module to the display controller.  
The parts for this PCB are available as service parts so this PCB can be repairable up to component level.  
1.2.5 Headphone PCB.  
This PCB contains the headphone socket.

WAARSCHUWING  
Alle IC´s en vele andere halfgeleiders zijn gevoelig voor  
electrostatische ontladingen (ESD).  
Onzorgvuldig behandelen tijdens reparatie kan de levensduur  
drastisch doen vermindern. Zorg ervoor dat u tijdens reparatie  
via een polsband met weerstand verbonden bent met hetzelfde  
potentiaal als de massa van het apparaat.  
All ICs and many other semiconductors are susceptible to  
electrostatic discharges (ESD). Careless handling during  
repair can reduce life drastically.  
When repairing, make sure that you are connected with the  
same potential as the mass of the set via a wristband with  
resistance. Keep components and tools at this potential.  
Houd componenten en hulpmiddelen ook op ditzelfde potentiaal.  
ATTENTION  
AVVERTIMENTO  
Tutti IC e parecchi semi-conduttori sono sensibili alle scariche  
statiche (ESD).  
La loro longevità potrebbe essere fortemente ridatta in caso di  
non osservazione della più grande cauzione alla loro  
manipolazione. Durante le riparationi occorre quindi essere  
collegato allo stesso potenziale che quello della massa  
delápparecchio tramite un braccialetto a resistenza.  
Assicurarsi che i componenti e anche gli utensili con quali si  
lavora siano anche a questo potenziale.  
Tous les IC et beaucoup d´autres semi-conducteurs sont  
sensibles aux décharges statiques (ESD). Leur longévite  
pourrait être considérablement écourtée par le fait qu´aucune  
précaution nést prise à leur manipulation.  
Lors de réparations, s´assurer de bien être relié au même  
potentiel que la masse de l´appareil et enfileer le bracelet  
serti d´une résistance de sécurité.  
WARNUNG  
Alle ICs und viele andere Halbleiter sind empfindlich  
gegenüber elektrostatischen Entladungen (ESD).  
Unsorgfältige Behandlung im Reparaturfall kann die  
Lebensdauer drastisch reduzieren.  
Sorgen Sie dafür, daß sie im Reparaturfall über ein Puls-

6.3.1 Description  
The intention of the electrical service diagnostics is to show the  
disc test is executed to check focus control, disc motor control,  
radial control and jump grooves control. The disc test is  
performed by audio play-back of 5 seconds at the beginning,  
middle and end of the disc.  
software versions present in the player and to direct the dealer  
towards defective internal units. The units are : the CDR main  
board, the CDR loader, the CD loader in case of a DR6050 and  
the keyboard/display board. A sequence of tests is executed  
automatically. Some of the tests can be aborted or skipped  
without the result being taken into account. External tools or  
disassembly of the unit is not necessary to get the diagnostic  
information. Pressing keys [PLAY/PAUSE] and [F FWD]  
simultaneously while switching on the unit, starts the test.  
Switching off the unit ends the test.  
CDR loader test  
During the test, the current disc time is shown. In case of an  
error the message "BERR1" will be displayed and the [F FWD]  
key must be pressed to continue with the following test.  
Pressing the [F FWD] key also aborts this test.  
CD loader test  
For DR6050 only. During the test, the current disc time is  
shown. In case of an error the message "BERR2" will be  
displayed and the [F FWD] key must be pressed to continue  
with the following test. Pressing the [F FWD] key also aborts  
this test.  
6.3.2 Requirements to perform the test  
Working keyboard to start up the test.  
Working local display to check the output messages.  
A CD-DA disc with a minimum of 3 tracks in all trays to  
perform the disc test.  
Display test  
All segments will blink at a frequency of 1 Hz. Pressing the [F  
FWD] key will start the next test because the user has to check  
for himself if all segments work properly.  
6.3.3 Description of the tests  
Keyboard and remote control tests  
Player information  
The test will give the user the ability to test every key without  
executing the function assigned to it. Therefore, the user needs  
to press every key on the keyboard and the remote control. The  
display will show the name of the key being pressed. Pressing  
more than one key at once will give an unpredictable result  
except for the service combinations : [PLAY/PAUSE] + [STOP],  
[PLAY/PAUSE] + [F FWD], [F FWD] + [REWIND], [ERASE] +  
[RECORD], [PLAY/PAUSE] + [RECORD].  
In this part of the test the following important information can be  
checked without removing the cover :

CDR communication test  
Figure 6-3  
Display : "DTST5". The communication between the host  
processor (DASP) and the CDR loader via the DSA-R-bus is  
tested.  
6.4.1 Description  
No external tools are required to perform this test. The cover  
needs to be removed because the user has to check the  
movements of the tray, focus and sledge visually. Pressing  
keys [PLAY/PAUSE] and [STOP] simultaneously while  
switching on the unit, starts the test. Switching off the unit ends  
the test. In case of a DR6050, one can check the CD loader  
mechanics in the same way by pressing the above key  
combination on the CD player keys.  
CD communication test  
Display : "DTST6"). The communication between the host  
processor (DASP) and the CD loader is tested. The test is only  
applicable for DR6050.  
Loader tests  
These tests determine if the CDR loader and the CD loader in  
case of a DR6050 w ork correctly. A CD-DA disc with a  
minimum of 3 tracks needs to be inserted in both loaders. A

simultaneously while switching on the unit. The player will  
erase a complete CD-RW disc (including PMA and ATIP lead  
out area) at speed N=2. The display shows the countdown of  
the remaining time required for the operation to complete. The  
format is "ER mm:ss", where "mm" are the remaining minutes  
and "ss" the remaining seconds. After completion the message  
"PASSED" is shown, and the player has to be switched off and  
on again to start up in normal operating mode. Switching off the  
unit before completion of the test, leaves the disc in an  
unpredictable state. In such case only a complete DC-erase  
procedure can recover the CD-RW disc.

6.4.3 Description of the tests  
Focus control test  
The focussing lens is continuously moving up and down. The  
display reads "BUSY".  
Sledge control test  
After pressing [F FWD] the sledge continuously moves up and  
down. Pressing [REWIND] stops the sledge at the position it is  
in and the focus control test resumes. The display reads  
"BUSY".  
6.5.2 Requirements to perform the test

Tray control test  
This test starts from within the focus control test routine.  
Pressing [OPEN/CLOSE] moves the tray in or out. In the tray  
open position one can initiate focus and sledge tests by  
pressing [F FWD]. One has to stop these tests pressing  
[REWIND] before it is possible to close the tray again.

Display controller TMP87C874F  
8.1 Display Board  
TMP87CH74F( QY01) is a high speed and high performance  
8-bit single chip microprocessor, containing 8-bit A/D  
conversion inputs and a VFT (Vacuum Fluorescent Tube)  
driver. In this application, its functions are :  
slave microprocessor.  
8.1.1 Description of display board  
General description  
The display board has three major parts : the FTD (Fluorescent  
Tube Display), the display controller TMP87CH74Fand the  
keyboard. The display controller is controlled by the DASP  
master processor on the CDR main board. The communication  
protocol used is I2C. So all the information between DASP and  
display controller goes via the SDA or I2C DATA and SCL or  
I2C CLK lines. Communication is always initiated by the DASP  
on the CDR main board. Unlike the previous generations of  
CDR players, the interrupt generated by the display controller  
at key-press or reception of remote control is not used. Instead,  
the DASP polls the display controller for these events.

input for remote control.  
All the communication runs via the serial bus interface I2C. The  
display controller uses an 8MHz resonator as clock driver.

Supply voltages  
Grid lines  
Level and timing of all grid lines, G1-->G15, can be checked  
either at the FTD itself or at the display controller. Grid lines  
G13, G14 and G15 each have an extra current amplifier in line  
: QY02 for G13, QY03 for G14 and QY04 for G15. A typical  
grid line signal shows in the oscillogram below.  
The display board receives several voltages via connector  
JY01.

•
VFTD : -35V 5% measured at pin 2 of conn. JY01.

+5V +5: V 5% measured at pin 10 of conn. JY01  
Voltages VFTD, VDC1 and VDC2 are produced in the power  
supply unit and sent to the display board via the CDR main  
board. The +5V voltage is produced on the CDR main board as  
D5V.  
+4V

Clock signal  
As clock driver for the display controller, a resonator of 8 MHz  
(XY01)is used. The signal can be measured at pins 8 and 9 of  
the display controller : 8 MHz 5%.  
-38V  
Control signals  
RESET  
The reset signal comes via pin 4 of conn. JY01 from the DASP  
master processor on the CDR main board (SYS_RESET). The  
reset is low active. It should be kept low during power up for at  
least 3 machine cycles with supply voltage in operating range  
and a stable clock signal (1 machine cycle = 12 x 1/Fc (8 MHz)  
sec.). During normal operation, the reset should be high (3V3).  
The high signal is 3V3 because the DASP operates on 3V3.

Figure 8-2 ‘I2C signals’  
FTD drive lines  
The lines connected to pins 34, 35, 36 and 37 of the display  
controller act as matrix scanners. Without a key pressed, they  
maintain a low level. As soon as a key is pressed, the scanning  
line connected to that key puts out a scanning signal, which  
should look like the oscillogram below. This scanning signal  
goes via the pressed key to I/O port 4 of the display controller  
(pins 28 to 33). The display controller can now determine which  
key has been pressed. Without a key pressed, pins 28 to 33 of  
the display controller maintain a high level (+5V).  
Filament voltage  
Should measure 3.8V 10%(=VDC1-VDC2) between pins 1-3  
and pins1-52 of the FTD(VX01).  
17  
The pulses created this way arrive at pin 16 and 17 of the  
display controller. The first pulse to arrive tells the controller the  
direction of the rotation. Counting the pulses reveals the  
amount of rotation. Combining and decoding this information,  
the display controller will execute the appropriate task.

Push button operation  
This button connects to the key matrix lines and thus the  
operation is identical to the ordinary keys. Without being  
pressed, pin 4 of the easy jog maintains the low level, pin 5 the  
high level. When pressed the scanning signal goes through the  
closed contact of pins 4 and 5, and can be checked at both  
pins.  
IR receiver - remote control  
In the CDR570/930 the IR receiver RPM6934-V4 (ZY01) is  
mounted on the display board. In all versions the IR receiver  
connects to the display controller. The signal coming from the  
receiver can be checked at pin 22 of the display controller. This  
signal is normally high (+5V). When the remote control is being  
operated, pulses mixed in with the +5V can be measured. The  
oscillogram gives an indication of how the signal looks like with  
the RC being operated.

cycle is regulated so that the output voltages are independent  
of load or input voltage variations. The controlling device  
MC44603 is an integrated pulse width modulator. A clock  
signal initiates power pulses at a fixed frequency. The  
termination of each output pulse occurs when a feedback  
signal of the inductor current reaches a threshold set by the  
error signal. In this way the error signal actually controls the  
peak inductor current on cycle-by-cycle basis.

Description of controller MC44603  
Pin connections  
The MC44603 is an enhanced high performance controller that  
is specifically designed for off-line and DC-to-DC converter  
applications. This device has the unique ability of automatically  
changing operating modes if the converter output is  
overloaded, unloaded or shorted. The MC44603 has several  
distinguishing features when compared to conventional SMPS  
controllers. These features consist of a foldback facility for  
overload protection, a standby mode when the converter output  
is slightly loaded, a demagnetization detection for reduced  
switching stresses on transistor and diodes, and a high current  
totem pole output ideally suited for driving a power MOSFET. It  
can also be used for driving a bipolar transistor in low power  
converters. It is optimised to operate in discontinuous mode but  
can also operate in continuous mode. Its advanced design  
allows use in current mode or voltage mode control  
applications.

Description  
Pin Name  
This pin is the positive supply of the IC. The operating voltage range after start-up is 9.0 to 14.5 V.  
The output high state (VOH) is set by the voltage applied to this pin.  
Peak currents up to 750 mA can be sourced or sunk, suitable for driving either MOSFET or bipolar transistors.  
The groundpin is a single return, typically connected back to the power source.  
The foldback function provides overload protection.

A voltage delivered by an auxiliary transformer winding provides to the demagnetisation pin an indication of the  
magnetisation state of the flyback transformer. A zero voltage detection corresponds to complete core  
saturation.  
Demagnetisation  
Detection  
The synchronisation input pin can be activated with either a negative pulse going from a level between 0.7V and  
3.7V to Gnd or a positive pulse going from a level between 0.7V and 3.7V up to a level higher than 3.7V. The  
oscillator runs free when Pin 9 is connected to Gnd.

The normal mode oscillator frequency is programmed by the capacitor CT choice together with the Rref  
resistance value. CT, connected between Pin 10 and Gnd, generates the oscillator sawtooth.  
10 CT  
A capacitor, resistor or a voltage source connected to this pin limits the switching duty-cycle. This pin can be  
used as a voltage mode control input. By connecting Pin 11 to Ground, the MC44603 can be shut down.

Operating description of MC44603  
The input voltage Vcc (pin 1) is monitored by a comparator with  
hysteresis, enabling the circuit at 14.5V and disabling the  
circuit below 7.5V. The error amplifier compares a voltage Vfb  
(pin 14) related to the output voltage of the power supply, with  
an internal 2.5V reference. The current sense comparator  
compares the output of the error amplifier with the switch  
current Isense (pin 7) of the power supply. The output of the  
current sense comparator resets a latch, which is set every  
cycle by the oscillator. The output stage is a totem pole,  
capable of driving a MOSFET directly.

When the input voltage of the IC exceeds 14.5V, the circuit is  
enabled and starts to produce output pulses. The current  
consumption of the circuit increases to about 17mA, depending  
on the external loads of the IC. At first, the capacitors at the Vcc  
pin will discharge because the primary auxiliary voltage,  
coming from winding 7-9 is below the Vcc voltage. At some  
moment during t2, the primary auxiliary voltage reaches the  
same level as Vcc. This primary auxiliary voltage now  
determines the Vcc voltage.

and stop sequence will repeat. The power supply goes in a

Regulation of P816  
Figure 8-14 shows the most relevant signals during the  
regulation phase of the power supply.  
The oscillator voltage ramps up and down between V1 and V2.  
The voltage at the current sense terminal is compared every  
cycle with the output of the error amplifier Vcomp. The output  
22  
is switched off when the current sense level exceeds the level  
at the output of the error amplifier.  
TimeON phase : A drain current will flow from the positive  
supply at pin 2 of the transformer through the transformer's  
primary winding, the MOSFET and Rsense to ground. As the  
positive voltage at pin 2 of the transformer is constant, the  
current will increase linearly and create a ramp dependent on  
the mains voltage and the inductance of the primary winding. A  
certain amount of energy is stored in the transformer in the form  
of a magnetic field. The polarity of the voltages at the  
secondary windings is opposite to the primary winding so that  
the diodes are non-conducting in this phase.

TimeDIODE phase : When the MOSFET is switched off,  
energy is no longer supplied to the transformer. The inductance  
of the tranformer now tries to maintain the current which has  
been flowing through it at a constant level. The polarity of the  
voltage from the transformer therefore reverses. This results in  
a current flow through the transformer's secondary winding via  
the now conducting diodes, electrolytic capacitors and the load.  
This current is also ramp shaped but decreasing.  
2
TimeDEAD phase : when the stored energy has been supplied  
to the load, the current in the secondary windings stops flowing.  
At this point, the drain voltage of the MOSFET will drop to the  
voltage of C821 with a ringing caused by the drain-source  
capacitance with the primary inductance.

The oscillator will start a next cycle which consists of the above

TimeDEAD is maximum with an input of 400VDC and a  
minimum load. It will be zero with an input of 100VDC and an  
overload.

Circuit description of P816  
Demagnetisation  
The auxiliary winding (7-9) voltage is used to detect magnetic  
saturation of the transformer core and connected via R801 to  
pin 8 of Q810. During the demagnetisation phase, the output  
will be disabled.  
Input circuit  
The input circuit consists of a lightning protection circuit and an  
EMI filter.  
The lightning protection comprises R819.  
The EMI filter is formed by C820, L820, C825 and C826.  
It prevents inflow of noise into the mains.  
Overvoltage protection circuit  
This circuit consist of D814, C814, R814, R815 and R816.  
When the regulation circuit is interrupted due to an error in the  
control loop, the regulated output voltage will increase  
(overvoltage). This overvoltage is sensed at the auxiliary  
winding 7-9.  
When an overvoltage longer than 2.0 (s is detected, the output  
is disabled until VCC is removed and then re-applied. The  
power supply will come in a hiccup mode as long as the error  
in the control loop is present.  
Primary rectifier/smoothing  
The AC input is rectified by rectifier bridge D802 and smoothed  
into C821. The voltage over C821 is approximately 300V.  
It can vary from 100V to 390V.  
Start up circuit and Vcc supply  
This circuit is formed by R823, R834, C829, D828, R829,  
R811,C833 and C811.  
When the power plug is connected to the mains voltage, the  
stabilised voltage over D829 (24V ) will charge C833 via  
R829.When the voltage reaches 14.5V across C811, the  
control circuit of Q810 is turned on and the regulation starts.  
During regulation, Vcc of IC7110 will be supplied by the  
rectified voltage from winding 7-9 via L832, D832 and C833.  
Secondary rectifier/smoothing circuit  
There are 5 rectifier/smoothing circuits on the secondary side.  
Each voltage depends on the number of windings of the  
transformer.  
The -8V supply is regulated by voltage regulator Q871.  
On/off circuit  
Control circuit  
The control circuit exists of Q810, C802, C804, C807, C809,  
C810, R802, R803, R804, R807, R808, R809 and R810.  
C802 and R810 define the frequency of the oscillator.  
Power switch circuit  
This circuit comprises MOSFET Q825, Rsense R826, R827 and  
pull-down  
R828, R825, C827, L825, R812 and R813. R825 is a  
MOSFET.  
resistor to remove static charges from the gate of the  
Regulation circuit  
The regulation circuit comprises opto-coupler Q801which  
isolates the error signal from the control IC on the primary side  
and a reference component D881.The TL431(D881) can be  
represented by two components:

TL431 will conduct from cathode to anode when the reference  
is higher than the internal reference voltage of about 2.5V. If the  
reference voltage is lower, the cathode current is almost zero.  
The cathode current flows through the LED of the opto-coupler.  
The collector current of the opto-coupler flows through R806,  
producing an error voltage, connected to voltage feedback pin  
14 of Q810.

The microprocessor controls the CD10 and is slave of the  
master processor on the CDR main board in the DR6050. Both  
processors communicate via a DSA connection (data, strobe  
and acknowledge).  
8.3 CD Main Board  
The CD main board is built around the compact disc  
mechanism VAM1250 and a loader 1250. The CDM delivers  
diode signals and an unequalised high frequency signal. These  
signals are necessary inputs for the decoder CD10. Based on  
these signals the decoder will control the disc. The decoder is  
able to control the sledge, focus motor, radial motor and turn  
table. When everything is "locked", the decoder delivers a  
digital output according to IEC958 standard, subcode to the  
microprocessor and I2S for reproducing analog audio signals  
by means of a D/A converter.

Description  
The CD main board receives +5V and +12V from the CDR main  
board via respectively pin 16 and pin 15 of connector 1208. The  
+5V is split up into +5VHF and +5V. The +5VHF is used mainly  
for the diode currents and the HF-amplifier. The +5V is used for  
the digital part of the board. On the board a +3V3 is made from  
the +5V for the decoder CD10 and an A3V3 for the DAC  
UDA1320. The +12V is split up into A12V for the audio output  
stage and +12V for the power drivers of the CDM.

The microprocessor has its own Xtal or resonator of 12MHz.  
The CD10 needs a clock of 8.4672MHz + 100ppm. This speed  
also relates to the disc speed. To avoid locking problems  
between the two drives in the CDR775, both drives run on the  
same clock. Therefore the CD main board gets the clock for the  
decoder from the CDR main board via pin 2 of connector 1208.  
The DAC needs a system clock to drive its internal digital filters  
and to clock the I2S signals from the decoder. In our case this  
is 11.2896MHz (CL11) generated by the CD10.

8.3.4 TDA7073A Power Drivers (7021, 7022)  
Description  
The motor driver 7020 can be measured dynamically by  
connecting a hall motor to the application panel. Apply a pulse  
of 1V 10Hz and 15% duty cycle to pin 22 (Ec) as input value  
with reference to pin 21 (Ecr=2.5V). Measure the output signals  
on the driver. This will give as response a square wave on pin  
17 and pin 18. When a positive voltage is applied, the square  
wave on pin 17 will go ahead of the square wave on pin 18.  
All signals will have a value as shown in the truth table. Check  
the following output signals :  
The TDA7073A is a dual power driver circuit for servo systems  
with a single supply. In this configuration it is used to drive the  
sledge, tray, focus and radial.

Description  
The tray control consists of a TDA7073A power driver (7021)  
controlled by the processor 7202 via pin 19 TRAYIN and pin 20  
TRAYOUT. If pin 20 is low and pin 19 high, the TRAY+ signal  
at pin 16 of 7021 is forced to +8V and the TRAY- signal at pin  
13 of 7021 to GND : the tray will open. If pin 20 is high and pin  
19 low, TRAY+ becomes GND and TRAY- becomes +8V : the  
tray will close. If pin 19 and 20 of the processor have the same  
value, TRAY+ and TRAY- will have the same value as well : the  
tray stops moving.  
Measurements

Description  
another amplification and filtering circuit. The filtering again is  
controlled by the S1 and S2 lines, dependant on whether the  
disc starts up (speed n=1, S1 and S2 Low), disc plays at speed  
n=1 (S1 Low, S2 High) or disc plays at speed n=2 (S1 and S2  
High).  
The pre-amplified HF-signal is presented to both n=1 and n=2  
amplifier circuits. The mux/demux switches via software and  
micro processor controlled S1 and S2 lines between either one  
of the amplified n=1 or n=2 signals. The signal will then follow

always happens on a falling edge of the CLK.  
The DAC used, is the UDA1320 bit stream, continuous  
DATA  
calibration. I2S signals from various formats can be entered at  
pins 1,2 and 3. If these signals are in phase with the delivered  
system clock at pin 6, the DAC will reproduce analog output  
signals at pins 14 and 16. 0dB level is 0.85Vrms. These analog  
signals are at 1.65Vdc level.  
The DAC has features which can be checked on the input pins.  
Mute will switch off the analog signals. De-emphasis is not  
used, since this is done in the decoder. Attenuation of -12dB is  
not used because this is also done in the decoder.  
DATA contains all data-bits. Data bits are set by the  
transmitting device, and read by the receiving device. The  
position of the DATA-bits within the WS-signal is very  
important. There are several formats for this. In our case we  
always use Philips I2S format, no Japanese or Sony format.  
The number of data-bits per channel depends on the used  
devices.  
Timing of the I2S-bus, in case of Philips I2S is shown in the  
next figure :  
I2S  
I2S is a kind of digital audio format, consisting out of 3 lines :  
CLOCK, WORDSELECT and DATA.  
LEFT SAMPLE  
RIGHT SAMPLE  
WS  
CLK  
WORD-SELECT  
Word select (WS) indicates whether the data-sample is from  
the left or the right audio-channel. It has the same frequency as  
the sample rate of the digital audio signal. This can be 32, 44.1  
or 48kHz. Normal polarity is low for a left sample and high for a  
right sample. So within the low state of the WS-line the data bits  
for the left channel are transferred, and within the high state the  
data bits of the right channel are transferred.

CLOCK  
The CLOCK signal (CLK) indicates when DataTips must be  
set, and when DataTips must be read. The frequency depends  
on the speed of the I2S-bus, but is always a factor of the  
frequency of the WS-signal. It can be 48x, 64x, 96, 128x... .In  
our case it is 48x the sample rate frequency = 2.1168MHz. The

Keep processor 7202 in reset by forcing pin 7 of connector  
1208 to +5V. This puts the processor outputs in tristate. Check  
the reset at pin 4 of processor 7202 to make sure that the  
processor is in reset.  
Now, force port 0-4 pin 33 at 7202 to 0V to set the decoder  
outputs (SCLK, WCLK, DATA, and CL11).  
Check the MUTE pin 11 at 7309 : this pin should be low.  
Connect via an I2S generator I2S-signals to the DAC :  
Pin 1 at 7309: SLCK.  
Pin 2 at 7309: WCLK.  
Pin 3 at 7309: DATA.  
Connect also the SYSCLK pin 6 at position 7309 to a clock  
signal of 11.2896 MHz 100ppm.  
Generate an I2S signal equivalent with a sine wave of 1kHz at  
0dB for both left and right channels.  
Check if 0.8 VRMS at pins 14 and 16 at location 7209 with a  
DC of 1.65VDC.  
Check if 1.7 VRMS 2 dB at connector pins 1and 3 at location  
1209.  
Force MUTE Pin 11 at 7309 high.  
Measure again at pins 1 and 3 at location 1209 : both signals  
should be at -90 dB.
