I assume the iDSD doesn’t do any re-clocking of the SPDIF signal from let’s say, an Google Chromecast?
Answer: That is incorrect. The input circuitry of the iDSD micro is exactly the same as the stand-alone SPDIF iPurifier. This means SPDIF signals are decoded, send into a memory buffer, de-jittered and then clocked out with the GMT Clock derived from the AMR DP-777.
