spdif (toslink) switch

Projects General Guidance

Hey all

Im thinking of making an spdif or TosLink switch. Im thinking of using the arduino to controll inputs to the output via an ir remote

ive ordered some of these toslink recivers

and the transmitter counterpart

the output will be going to a Schiit DAC then to my amp

Would the arduino be capable of doing the switching or would a different micro controller be chosen?

Circuit?

i been reading about mux looks like it will do what i need but cant find a digital one with enough inputs

Most analog MUXs will handle a digital signal, as it's exactly the same as a 0 - 5V square wave analog signal. The maximum frequency and peak-to-peak voltage is what you need to look out for.
