Hello everybody.
I'd like to reclock my superdac and got the most figured out. One
downside is that it will only play on 44.1kHz after modification, but
that's fine with me.
The next things need to be done:
Make pin 23 of the cs8414 high so that fsync en sck become an input.
R25 should be taken loose from the cs8414. The new clock signals mclk,
lcrk and bick can be generated with an stable 11.289Mhz clock and a
74HC4040 frequency divider.
The only thing I'm a bit concerned about is pin 9 (dsf) of the ak4393.
I thought it should be low during CD playback, but it isn't. It should
run at normal speed right? (datasheet ak4393 page 10) My cd player
really puts out 44.1kHz!
