Clicks and pops when using external clock with the ADA8824 (ADAT) 24-bit Eight Channel A/D-D/A Converter?
Determine which external clock (AES1 thru 3, S/PDIF, WORD, ADAT optical) is causing clicks. Its entirely possible the ADA8824 is working correctly but that the clicks are occurring somewhere else in his system, or that there is a sync issue with the system (master/slave stuff, etc). There can be only one master device in a clocking system, all others must slave to it either directly or indirectly. Additionally, when using AES input, ensure that all AES sources are in sync (referencing the same clock source themselves).
