In order to externally clock a Yamaha 01V, the S/PDIF digital input has to be used. Now I only want to use this as a clock source, so I wanted to built a S/PDIF clock generator. The ART SyncGen has the features I'm looking for.
If I could simply create a signal with a clock frequency of 64*48000 (where 48000 Hz is the desired sampling frequency, all the data bits are now '0'), it could be done with 7400 logic. But to really implement the S/PDIF protocol, I have to insert a preamble and all that stuff. I could buy a dedicated chip for this purpose, but don't know what my best option would be.
Anyone knows somewhere to start? Help is appreciated!🙂
Kind regards,
Laurens

I'd just throw down a Cirrus CS8406 chip.
Feed it a clock, strap pins on it to put it in hardware mode as an I2S master, ground the audio input.

One question though: should I feed the I2S bus a SCLK signal? I thought that the system might turn off or something when you don't supply an I2S clock. Or is the clock supplied to the CS8406 simply enough (since it's already the timing source for the S/PDIF signal)?
