Have a look at the schematic for Rotel RCD-975 (dual TDA1305) CD player (mid 1990s ???).
The serv. manual is a bit hard to follow from the way it is presented. In any case ...
The RCD-975 uses one TDA1305 for each stereo channel. (The 1305 is stereo dac with WS input).
The WS (combined -- single wire), signal from a SAA7310 decoder.
It is a bit unclear in how L/R data is presented to each L and R dac (WS) input.
On page 12 of the SM, there seems to be some massive 74HC glue logic going on. Not sure how much of this is related to slicing up WS into L and R separate components. Didn't know this was possible on a glue logic level. Maybe it's trivial. I've never seen the TDA1305 used in a such a way (two: L and R separate channels).
