Just acquired a DCD-500 which has a PCM54HP R2R DAC.
The transport and controls look cheap and I suspect 25 odd years hasn't done them any favours. The slightest nudge throws the tracking off entirely.
I'd like to be able to use the DAC with a newer and more reliable CD player which has a SPDIF output. Initially just try it in situ and if I'm happy with it, build it on a new PCB down the track.
I've found what appears to be the PCM signal feeding a CX23035 chip which then drives the parallel R2R DAC.
So, how do I get from SPDIF to PCM? I found some chips which do the job, is that my only option or are there any pre built modules for this? If I use a chip how to build or find an optical receiver? Thanks in advance [emoji4]
