An S/PDIF Sound Card Using PCM2906
https://www.electronics-lab.com/an-spdif-sound-card-using-pcm2906/
joesugar @ ceworkbench.wordpress.com has designed a S/PDIF Sound Card using the PCM2906 IC. In the belief that I’d rather build than buy I decided to update one of my previous projects, a PCM2904 based sound card, to include an S/PDIF interface. The update was a cinch because TI has a pin-for-pin replacement for the PCM2904 (the […]
