AK4113 + CS8416 Digital-Receiver SPDIF to I2S converter+ software control + 1602 LCD wiring-diagram
after i looked about some cheap SPDIF (Coax+opt) to I2S converter, i came across these 2 birds:
AK4113: (10$ at Ebay & Aliexpress)and CS8416: (12$ at Ebay & Aliexpress)
they are both capable of max 192khz input and u can select the input-port via the „BUT“-port switch..
The LCD-display should show the Input-Line and the sample-frequency..
and because there were no wiring diagram on the sellers-site i searched a bit/lot and found some wiring-diagrams for these 2 on audiophonics.fr..
(just in case there were also google-user who are interested in such a diagram)
