IC or PIC for receiving a S/PDIF signal to RPi - Raspberry Pi Forums


i'm creating program processes pcm of s/pdif raspberry pi 2(the goal receiving 5.1ch surround, i'm studying basic currently).

however, since throughput of rpi's gpio(5mhz in c) less frequency of s/pdif(about 16 mhz), can't receive directly.

therefore, i'm examining way pre-processing before send signal. if know ic or pic(*i know digital sound boards rpi. but, little expensive) can solve it, please tell me.

the cheapest from

luck decoding multi-channel 5.1ch less fast dspic

far easier usb sound card multi-channel in. cheaper too.
