Overview
The DiVa DV78 is a completely new design platform
that share a similar circuit topology to the earlier
released Vaddis V based players such as the Diva
88+, Diva 89, DV27.
The player is based around acclaimed Zoran Vaddis
Vchipset coupled to high specification Wolfson D to A
converters for Left and Right channels.
Power supply board.
Non-switching
Mains power arrives at IEC inlet socket SKT1 and is
filtered by EMC choke LI and Y caps C3 and C4,
mains switch SW2a/b switches both Negative and Live
phases before the power reaches the mains select
switch at location SW1 the switch allows the primary
windings of the transformer TX1 to be wired in either
Parallel or Series configuration.
The Bridge rectifying Diode package at location D1
forms the basis of the conventional power stage and
supplies a VN35V6 (-35.6v) to the Switch mode
stage, transistor TR1 is biased by 2v7 Zener diode
DZ1 and allows for the series Zener diodes DZ2, DZ3,
DZ3 to supply the VN13V5 and VN19V rails.
We will also see a simple A.C present circuit this is
used for delayed output relay operation and fast relay
closure under interrupted supply conditions thus
preventing op-amp offsets from reaching the Audio
output sockets.
Switch mode
The switch mode supply is formed around the
Driver/Control chip IC1 UC3843 (used in regulating
mode). The chip is referenced the –36.5V supply line
and the Digital ground DGND, the supply for the chip
is formed by the 12v Zener at location DZ6 and can be
seen on Pin 7 as VCC. The power supply allows for
the switch-mode to be tied the to Audio sampling
frequency for any given compatible format.

The PSU sync signal is driven into the power supply via
Resistor R9 if no Sync is present the unit is set to free run x
due to the RT/RC network attached to Pin 4.
IC1 is running in regulated mode and monitors the voltage
output on the +5V and +3V3 D.C lines, the two voltages are
summed by TR8 and Driven into the VFB and Comp inputs
of IC1, the Voltage is then regulated by changing the time
base of the PWM output at pin 6 (longer the time base the
lower the voltage), the PWM switching frequency is driven
into the switch-mode transformer by the high speed Nmos
device at position M1, R5 is used to sense the Current
across the gate of the Nmosfet and in the event of a short
circuit will safely shut the power supply down. We derive the
12v Mech supply from the output of M1 using the Ultra-fast
Diode at location D8 to rectify the PWM line.
The D.C outputs from the switch mode have extensive
switch mode noise removing filters these are seen as 100n
caps down to ground and Wire wound inductors in series
with the supply rail.
Power supply main board
All the power supply rails are supplied to the main board via
the 32 way FFC connector at location CON1001.
The Digital supplies from the switch mode stage of the
power supply arrive as 3V3D, +5VD and +12VD we also see
the Display board power supplies arrive as –19V, -9 and
–13.5V all of the supplies have a second stage of
implemented on the board to remove all traces of ultra-sonic
noise.
The 3V3D rail is the main 3V3 rail used to power the digital
circuitry; +5VD is used for all 5v Digital/Video supplies the
+12VD is used for Scart switching.
Diva Dv78 circuit description

The 1V8 rail is derived from the 3V3 rail and is
regulated by the adjustable regulator at location
REG1003.
The Analogue supply stages arrive at the main board
as +15V3 and –15V3 rails these are filtered L1002 and
L1015 before being regulated by the adjustable
regulators at locations REG1000 and REG1002 to
provide +/- 12V rails for the Analogue output stage.
Regulator REG1001 is fed from the +15V3 rail and
forms the Audio DAC supply.
The Display board requires several supply voltages
these are simply passed through the main board,
being filtered on the way to prevent transmission of
noise through to the surrounding electronics. The
display takes the +5V, -19V, -13V5 and -9V the –13V5
and –9V form a floating 4.5V supply biased relative to
the –19V grid voltage.
Display Board
The main component of the Display board is IC1 this is
a Vacuum Florescent Display driver with keyboard san
and a serial data in/out interface.
The Chip receives display drive serial data from the
Vaddis V chip on the main board via Con1 on pins 12,
13 and 14 these will be seen a DIN, STS and CLK this
data is used to drive the VFD a DOUT line interfaces
with the VADDIS V and supplies Keyboard Scan
information. The keyboard scan is a 6 x 4 matrix with
the Key Source appearing at S3, S4, S5, S6 and the
Keyscan data returns appearing a K2, K3 and K4.
Please see: above for power supply information.
The Infra red pick-up at location RXI receives RC5
data and send the data to the Vaddis V on the main
board via transistors TR2 and TR3, LED 2 is used to
mix the rear panel RC5.
The rear panel 3.5mm input jack receives modulated
RC5 code; this is filtered for ultra sonic noise by the
inductors at locations L900 and L901 and then passed
to the Infrared diode on the display at location LED2.
Main Board electronics DV78.
Zoran Vaddis V.
The main processor/control chip on the main board is the
Zoran Vaddis V at location IC202, this is the latest
incarnation of the very popular Vaddis range of processors
and allows for a much lower component count when
compared to our earlier players as many of the playback
functions have moved onto the Vaddis V silicon.
Below you will see the major functions of the Vaddis V
when used with the DV78.
o Decoded Analogue Video output (internal
DAC) used on the DV78 only.
o SPDIF output.
o Internal display interface.
o Internal ATAPI interface.
o Internal IR interface.
o Serial in/out for RS232 (Optional).
A more detailed explanation of the Vaddis V and
peripheral components follows.
Vaddis Power
The Vaddis V is powered by two separate supplies the
Vaddis requires a 1.8v supply for the core, this is regulated
from the 3.3v rail by REG1003, the 3.3v rail is used to
supply power to the I/P – O/P ports of the chip.
ATAPI interface
CON203 is an ATAPI interface on a 40 way IDE
connector. This is decoupled from the Drive via an array of
decoupling resistors as required by the ATAPI spec.

Display Board interface
The display board interface is on the 16 way FFC flexi
foil connector at location CON202. Power for the
display also travels on the connector. There are 4 –
wires to interface with the VFD driver chip these are
seen as.
o XFPDIN - Data to the display board
o FPDOUT - Data from the display board
o XFPCLK - Clock
o XFPSEL - Chip select
The above control lines are level shifted to 5v logic
from 3.3v levels by IC200 (74HCT125) these are the
levels required by the VFD drive chip.
The IR output from the Display board arrives as
IRRCV this is an open collector signal, which can be
wire-Ord with the re-panel remote input.
Digital Audio
The Digital audio leaves the chip as 1 data line
labelled as.
o ADAT0 - Left and Right channel data
Along with the ADAT line we will also see the ABCLK
and ALRCK as required for IS2 data conversion.
The Vaddis V also supplies a direct SPDIF output for
interfacing with ancillary processing equipment.
Flash/ SDRAM
IC203 is a 64Mbit (32 bit x 2Meg) SDRAM. It runs at
135MHz
IC205 is a 16Mbit (16 bit x 1Meg) intel type flash IC for
program storage (Player software).
The flash interfaces to the Vaddis V using the SDRAM
bus it may appear that the bus connects to the flash in
a random manner, however this is simply because the
Vaddis bus is multiplexed that way. The Flash will be
accessed at power up and the contents are copied to
the SDRAM the program will then be run from the
SDRAM.
Series resistors are employed to isolate the flash bus
from the main SDRAM bus.
EEPROM
IC204 is a 8kBit (1K x 8) Serial EEPROM. This is used
for storage of non-volatile storage of player settings,
region settings and bookmark data.
Clocks
CLK27MV is the 27Mhz clock for video. It is used to
generate the 135Mhz clock for the Vaddis microprocessor
and DSP. The MCLKV is the audio master clock for the
Vaddis.
We run the Vaddis in PLL bypass mode and generate or
own master clock (see main clock section of manual) for
higher accuracy and improved performance across Audio
and Video.
RESET
IC201 is a reset generator chip that monitors the +3.3V rail
and ensures a reset signal PWR_ON_RESET* is
generated on power up, or if the mains power dips below
an operational level.
This signal is used to reset the Vaddis V and Flash micro
only. The Vaddis V line labelled as RESET* resets the
remaining circuitry of the player apart from the HDMI chip,
this has it’s own reset line labelled as HDMI_RESET this is
necessary if we require to reset the HDMI chip only (for
example when the HDMI sink is connected and then
disconnected).
Serial Port
The VADDIS V can interface with the external world via
the RS232 connector at location CON900 and the RS232
Transceiver at location IC900, the serial data lines are
shown as SERIAL RX and SERIAL TX these lines allow
for direct control over the unit via RS232.

Clocks and SPDIF stage.
IC300 is a PLL1700E clock generator IC the chip is
powered from the +5V(D) rail. The Chip runs in
software mode and is slaved from the Vaddis V (data
coming in on the MD line).
X300 is a 27Mhz crystal that IC300 uses to generate
all the video and audio clocks required by the system
the crystal sits on the XTI and XTO pins of the chip,
the 27Mhz output at Pin 10 (MCKO) is used to drive
the Vaddis chip directly bypassing the internal PLL.
The frequency of the audio master is dependent on
the on the current audio sample rate (I.e the sample
rate required by the format CD=44.1Khz and
DVD=48khz etc) and this is set by the system micro
via the MD, MC and ML_1700 lines from the Vaddis V.
Clock Buffer
IC301 us used to buffer the audio master clock. The
circuit is arranged so that each device that requires
the audio master clock has it’s own driver these are
seen as.
o MCLK_DAC0 - Pin 18
o MCLK_DAC1 – Pin 16
o MCLK_DAC2 – Pin 14
o MCLK_VADDIS – Pin 3
o MCLK_HDMI – Pin 9
We also run the Mute Line from the Vaddis V IC301
this can be seen on Pin 12 and drives transistor
TR401, the transistor pulls the relays RLY400,
RLY500, RLY600 to ground and un-mutes the audio
outputs.
IS2 Audio Data
IC302 and IC309 are buffers for the 12S signals these
ensure that the signals travelling to the DAC’s are
point to point. IC302 deals with the ALRCK and
ABCLK and IC309(NF DV78) the
ADAT0,1,2 all signal are split into three separate lines
for the three stereo DACS.
PSU Clock Divider
IC304 a/b form a clock divide by 1, 2 or 4 to ensure
the PSU clock is always either 44.1kHz or 48Khz (See
fig 1 within the power supply description section).
The circuit is fed from the ALRCLK (Audio clock) the
selected PSUCLK is controlled by PSUFSO and
PSUFS1.
The output of the PSU circuit can be seen to leave
IC305 on pin 5 via R311. Please see Fig 1 for PSU
control information.
The circuit will also switch the PSUCLK off when switching
between sample rates (the PSU will free run when the
PSUCLK is not present).
SPDIF Output
The SPDIF output consists of IC901 implemented as a
inline buffer and parallel output buffer. Gate A buffers the
signal so that the SPDIF line from the VADDIS sees fewer
loads and form a feed to the Optical output transmitter,
gates B,C and D drive the SPDIF in parallel so that we can
drive a 75ohm load adequately. The resistors at the output
of IC901 are arrange so that the output will be 500mV pk-
pk when the output is terminated with a 75 ohm load at the
same time the output impedance of the circuit is 75ohms
as required by the Sony Philips Digital Interface
specification.
Left and Right channel D to A stages
The Wolfson WM8740 stereo DAC ay location IC403
requires +5V(A) and a +3V3 supply along with the Digital
Audio data lines already described in this guide.
The Left channel output only will be described in this
section.
IC400B and associated components form a 2
nd
order
Bessel filter with a differential input and a gain of 1 this
follow by a output buffer IC401B, the gain of IC401B is
control by the switching chip at location IC402, in normal
use the Gain of IC401B is set to 1.1 but in HDCD mode
the IC402 switches a second 10k resistor in parele with
R413 and the gain is set to 2.2 allowing for the higher
audio output required by the HDCD standard.
C436 is an A.C coupling capacitor used to remove the few
mV of offset that the DAC produces; D400 provides
protection against from ESD.
The all output relays are under control of the Vaddis V
chip but will also mute the outputs instantly under mains
failure conditions. Switching drive is provided by TR401
(MUTE_BUF) and TR400 (AC_PRES) the relays are in
mute mode if either the input to TR401 is Low or if the
input to TR400 is high.
Please note: The Scart left/right audio is fed from the
outputs of the left/right audio stages.

Video Output stage
The DV78 video output stage makes use of the
VADDIS V’s on board video DAC stages and as such
does not use the superior Analogue devices video
encoder DV79/DV29 and is fed by the following video
lines from the Vaddis V.
o Composite
o SVID_C
o SVID_Y
o V or Red
o U or Blue
o Y or Green
If we look at the Composite stage only, we will see that
the Analogue video signal is filtered by C710, C711
and L705 before being passed through the Video Op-
amp at location IC701 the output is decoupled by
capacitor C738 before reaching R714 this forms the
75 ohm load required. All other video outputs are
identical.
SCART Output
RGB and Composite video signals as well as Left and
right audio signals are all present on the SCART
output socket. As the RGB and YUV signals share the
same output port at the Vaddis V the player must be
set to RGB SCART operation to have a RGB output
on the SCART.
Please note: When in RGB SCART mode the RGB
does not contain a Sync signal and the sync must be
taken from the Composite out (4 wire RGB).
Also present at the Scart are a number of control flags
for the monitor these include 2 GPIO control lines
direct from the Vaddis.
o ENABLE_AV
o 16/9
These are seen at the SCART output pins as.
o O/6/12
o RGB STAT
The 0/6/12 line (SCART pin 8) is used to inform the
monitor of the screen format being sent by the player
as set in the video set-up section of the software.
o Standby = 0V
o 16:9 aspect ratio = 6V
o 4:3 aspect ration = 12V
The RGB status line (SCART pin 16) will be seen as
0v = no RGB and >1v is RGB present.
