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 I C connection to the main
microprocessor on the CDR loader module. Information which needs to be displayed is also fed via this I 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.

3. WARNINGS

WARNING

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.

ATTENTION

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.
Veiller à ce que les composants ainsi que les outils que l´on
utilise soient également à ce potentiel.

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 Puls­armband mit Widerstand mit dem Massepotential des
Gerätes verbunden sind.
Halten Sie Bauteile und Hilfsmittel ebenfalls auf diesem
Potential.

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.
Houd componenten en hulpmiddelen ook op ditzelfde potentiaal.

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.

6.3.1 Description

The intention of the electrical service diagnostics is to show the
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.

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.

6.3.3 Description of the tests

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.

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.

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.

Player information

In this part of the test the following important information can be
checked without removing the cover :
Recorder ID.
SW-version back end of player.
SW-version CDR loader.
SW-version CD loader (only for DR6050).

CDR main board test

[F FWD] key. The message "DERRn" will be displayed with n
indicating the faulty test number.
If one of the tests is aborted with the [F FWD] key, no error
message will be displayed for this test. The flash data erase
test ("DTST3") can not be aborted !
The CDR main board test consists out of :

DRAM test

Display : "DTST1". The DRAM used for buffer management is
tested by writing, reading and verifying test patterns.

Flash checksum test

Display : "DTST2". This test checks the checksum of the
player's SW stored in the flash.

Flash data erase

Display : "DTST3". During this test, all temporary information
(CDtxt) in the flash is erased.

CODEC (ADC/DAC) test

Display : "DTST4". This test checks the CODEC IC by writing,
reading and verifying test patterns. The test is not applicable for
CDR950.

Keyboard and remote control tests

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 and the focus control test resumes. The display reads
"BUSY".

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.
Depending on the action the display reads "OPEN",
"OPENED", "CLOSE" or "BUSY".

6.5 DC-erase service mode

This test is initiated by pressing [ERASE] and [RECORD]
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.

6.5.2 Requirements to perform the test

8.1 Display Board

8.1.1 Description of display board

General description

The display board has three major parts : the FTD (Fluorescent
Tube Display), the display controller TMP87CH74F and 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.

8.1.2 Test instructions

Supply voltages

The display board receives several voltages via connector
JY01.

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

• VDC1-VDC2 : 3V8 ±10% measured between pin 1 and 3 of
conn. 1119.

• +5 V : +5V ±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.

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%.

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.

I2C DATA/I2C CLK

These lines connect to the DASP master processor via
respectively pin 5 and pin 7 of conn. JY01

. When there is no
communication, they should have the high level (+5V). The
oscillogram below gives an indication of how these signals
should look like.

Figure 8-2 ‘I2C signals’

FTD drive lines

Filament voltage

Should measure 3.8V ±10% (=VDC1-VDC2) between pins 1-3
and pins 1-52 of the FTD(VX01).

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.

Figure 8-3 ‘Gridline’

Segment lines

Level and timing of all segment lines, P1-->P21, can be

checked either at the FTD itself or at the

display controller.

The data on these segment lines however,

characters displayed. The oscillogram below

shows a

segment

line with data. A segment line without data

maintains

a -38V level.

Figure 8-4 ‘Segment line’

Key matrix 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).

Easy jog knob

Rotary operation

The easy jog knob (SY26) incorporates a whole heap of user
control possibilities in just one knob. Without the knob being
operated, pin 1 and 3 of the knob (and thus pin 16 and 17 of the
display controller), maintain the +5V level. Turning the knob
clockwise briefly connects pin 1 to GND followed by pin 3.

290799

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.

8.2 Power Supply Unit P816

8.2.1 Description of P816

MOSFET Q825 is used as a power switch controlled by the
controller Q810. When the switch is closed, energy is
transferred from mains to the transformer. This energy is
supplied to the load when the switch is opened. Through
control of the switch-on time, the energy transferred in each

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

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

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.

When the overvoltage protection pin receives a voltage greater than 2.5V, the device is disabled and requires a
complete restart sequence.

A voltage proportional to the current flowing into the power switch is connected to this input.

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.

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.

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.

A voltage level applied to the RP Standby pin determines the output power level at which the oscillator will turn
into the reduced frequency mode of operation (i.e. standby mode). An internal hysteresis comparator allows to
return in the normal mode at a higher output power level.

The error amplifier output is made available for loop compensation.

This is the inverting input of the Error Amplifier. It can be connected to the switching power supply output
through an optical (or other) feedback loop.

The reduced frequency or standby frequency programming is made by the RF Standby resistance choice.

Rref sets the internal reference current. The internal reference current ranges from 100 A to 500 A. This
requires that 5.0k

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.

t1: Charging the capacitors at Vcc
C829 will be charged via R823 and R832, C833 and
C811 v ia R829. The output is switched off during t1.
t2: Charging of output capacitors
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.
t3: Regulation
The output voltage of the power supply is in regulation.
t4: Overload
When the output is shorted, the supply voltage of the circuit will
decrease and after some time drop below the lower threshold
voltage. At that moment, the output will be disabled and the
process of charging the Vcc capacitors starts again. If the
output is still shorted at the next t2 phase, the complete start­and stop sequence will repeat. The power supply goes in a
hiccup mode.

The voltage at the current sense terminal is compared every

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.
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
described three phases. The time of the different phases
depends on the mains voltage and the load.
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

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.

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.

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.

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.

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.

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

Power switch circuit

This circuit comprises MOSFET Q825, Rsense R826, R827 and
R828, R825, C827, L825, R812 and R813. R825 is a
resistor to remove static charges from the gate of the

pull-down

MOSFET.

Regulation circuit

The regulation circuit comprises opto-coupler Q801 which
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:
a very stable and accurate reference diode
a high gain amplifier

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.

+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.

8.3.2 Clock Signals

Description

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.

8.3.5 BA6856FP Turn Table Motor Driver (7020)

Description

This component is a 3 phase, full wave pseudo linear driving
system with inbuilt Hall Bias circuit and 3 phase parallel output.

Measurements

Keep processor 7202 in reset by forcing pin 7 of connector
1208 to +5V. The outputs 9, 10, 11 of connector 1006 are 0V.
Pin 21 of the motor driver 7020 is 2.5V
Pin 22 of the motor driver 7020 is 2.5V

± 10%.
± 10%.

Pin 23 of the motor driver 7020 is 0V.
Pin 19 of the motor driver 7020 is 5V

± 10%.

Put the processor out of reset to continue the measurement.
Check MOT1 at pin 59 of CD10. The duty cycle of the output
should be 50%. Check wave form at pin 11 of 7005-D :
amplitude 5V + 5% duty cycle 50%.
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 :

8.3.6 Tray Control

080999

080999

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

Keep procesor 7202 in reset by forcing pin 7 of connector 1208
to +5V. Connect a load of 15 , 7W between pin 3 and 4 of
connector 1002. Check the voltage over the load with TRAY+
(pin 3) as positive reference. Check also the levels of pins 19
and 20 of the processor.
U TRAY+,TRAY- = <100mV
Pin 20 = +5V
Pin 19 = +5V
Force pin 20 of the processor to ground, and check the
voltages.
U TRAY+,TRAY- = -6.5V( 10%
Pin 20 = +0V
Pin 19 = +5V
Force pin 19 of the processor to ground as well and check the
levels again.
U TRAY+,TRAY- = <100mV

8.3.7 HF Path

Description

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

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).

8.3.8 Audio Part - DAC

Description

The DAC used, is the UDA1320 bit stream, continuous
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.

I2S

I2S is a kind of digital audio format, consisting out of 3 lines :
CLOCK, WORDSELECT and DATA.

of 500 kHz, 1Vtt. Check this AC value with an AC mV-meter :

CL96532086_060.eps

signal is in phase with the WS-signal. Transition of the WS
always happens on a falling edge of the CLK.

DATA

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 :

LEFT SAMPLE RIGHT SAMPLE

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

NMUTE

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
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
