PCM4222EVM: Unknown clock oscillator on received board

Part Number: PCM4222EVM

Hi, According to the BoM, the board has two Pletronics oscillators, in particular SM7745HSV-22.5792M. However on the board received I can see something else was used. Unfortunately I couldn't identify it, so maybe you could clarify it for me? It's black and has only markings "22.57CO2 TXCB0FL8".

    Hello,

    The oscillators on these EVMs occasionally become unavailable for periods of time and we have to find alternatives.  Are you having issues with the board operation, or are you only asking to see if there what alternative could have been used?

    We pulled the official build BOM down from the archives and it still shows the SM7720HEV-24.576M  as the desired part# to use.
