FMJ Dv29 Circuit description. Overview The DV29 is effectively a no compromise version both electronically and mechanically of the DV79. The player is based around acclaimed Zoran Vaddis V chipset coupled to high specification Wolfson D to A converters for all six audio output channels, also featured in this design is a HDMI transmitter with digital Video and a Audio output capable of Digital Surround.
PAGE 4
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.

Display Board interface Flash/ SDRAM 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. IC203 is a 64Mbit (32 bit x 2Meg) SDRAM. It runs at 135MHz o o o o XFPDIN - Data to the display board FPDOUT - Data from the display board XFPCLK - Clock XFPSEL - Chip select The above control lines are level shifted to 5v logic from 3.

Left and Right channel D to A stages The Wolfson WM8740 stereo DAC 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 as all audio output stages are the identical (all six channels of a DV79) apart from the HDCD gain switching for L + R only.

HDMI output stage Please note: Due to the plug and play nature of the HDMI/DVI interface, if presented with a reported no HDMI problem it is worth checking all set-up parameters of both the DVD player and the Plasma/Projector in use before performing component level diagnostics on this section. HDMI is a system that transmits uncompressed digital video and digital audio over a high speed encrypted interface.
PAGE 9
Comms and Final video output stage The signals from the main board travel up to the Comms board on connector CON902. The Video signals simply travel via an A-C coupling net before exiting the player via the RCA-phono sockets at locations SKT902 and SKT903. The RS232 interface is on 9 way “D” type CON900, with IC900 providing the level translation and static protection between the RS232 levels and the 3.

Transformer Specification for 115/230V 50/60Hz mains transformer. Arcam Part Number L924TX The transformer is extremely cost sensitive. It is to employ the most cost effective techniques to achieve the specification. The transformer output voltage will be regulated by a switch mode power supply. 330MM The only essential specification is the fact that it must produce no acoustic noise either internally or by induced eddy currents in steel chassis etc..
