The DV29 uses a separate isolated Toroid transformer and Rectification stages based around Bridge rectifiers DBR1000 and DBR1001 and bulk smoothing caps C1048 and C1049 to supply the Analogue stages the smoothed D.C output from this stage is fed L1013 (+) and L1015 (-).

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, this is covered in-depth within the Coms and Video output section of this guide.

Main Board electronics

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

o20 Bit digital video output for external Video DAC’s and HDMI output stage.

oDecoded Analogue Video output (internal DAC) used on the DV78 only.

oDigital Audio output 3 data lines 6 channels for internal L + R DAC’s and L + R + C + LS + RS for DV79 and DV29 also used for HDMI for the DV79 and DV29.

oSPDIF output.

oInternal display interface.

oInternal ATAPI interface.

oInternal IR interface.

oSerial in/out for RS232 DV79/DV29

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.
