I'm planning on doing some modifications to a low-end CD player
(Teac PD-165) for research purposes. I'd like to add serial digital
output to the unit. It looks like the decoding/error correcting/etc.
chip - a Yamaha YM3805 has a straight serial out. However, the
Teac service manual gives only a block diagram of the device and
not all pin numbers are listed on the schematic.

Specifically, I'm interested in the output format of the SDO (Serial Data
Out ???) pin - it's the input to the digital filter so it should have
the data I'm after. Also, I'm interested in the output data format on the 
QOUT pin. I know its 4X oversampled and it appears that the data format is 
24 bits per channel plus a sync bit.

I'd also like some information on the timing of the SAMP1 and SAMP2 pins.

If anyone knows where (or if) I can get a data sheet on this chip or can
answer any of the above questions - I will be most grateful.

Thanks,
Todd.
