I recently acquired an NEC 602 cdrom drive. I would like to entirely remove the S/PDIF interface from the output. As per a suggestion in this thread :
http://www.diyaudio.com/forums/showthread.php?s=&threadid=18786&perpage=15&highlight=nec+602&pagenumber=1
I would like to hook up the LRCLK, DATA and SIN outputs from the Sony CXD2510 IC directly to a TDA1543A. However, I can't find any TDA1543A's for sale. Are their any replacements which can take the same Sony data format on input and sound at least as good? If not, what other options do I have open to me?
Additionally, would a 74x IC buffer on input of the TDA1543A be of any benefit? I believe it was said that the digital signal on the DATA line is not as clean as it could be coming out of the CXD2510.

vcch said:TDA1543A accepts 24bit right adjusted format which data is 16bit two's complement with MSB first.
I have tried other formats, it doesn't work.
As do many other dacs. What makes the the Sony format different is the fixed 48Fs serial clock.
