Sony CXD9544 and CXD9543 pulse DACs
Does anyone have any data on these, or, say, a service manual for a DVD player or similar, that uses them (Like the DVP-NS535)?

I have the service manual for a more modern SACD capable player which uses CXD9744 and 9743, as far sa I can see, at least the 9744 seems largely pin-compatible with the 9544, except for the DSD inputs.

The 9544/9744 is a stereo DAC in a wide SO20 case, the 9543/9743 s a 6-ch DAC in a TQFP44 case... They all use diferential PCM voltage outputs.

Sadly, no help there. The models that used these DACs are older generation (black, perhaps 3-4 years ago) with built-in 5.1 decoding...
