Hello,

I'd like to use a DIR1701 or DIR1703 ( which one would you recommend ? ). It's connected to a I2S interface on a SoC and some GPIOs.

I'd like to have both opto and SPDIF output with only one chip, It would be nice if it was 'autodetect' but I can also select which one is active with one simple GPIO.

Also, It has to be with the best quality possible and SPDIF should be electrically isolated with a transformer I suppose.

Can some one help me ?


Thanks,
Sylvain Munaut
