Hi guys,
Just received this PCB which I bought on a whim thinking it would be fun to experiment with, but now the seller is telling me he can't supply the schematic. Does anyone out there have the schematic for this very common 1541 DAC PCB? I have contacted multiple vendors of this with no reply.
Thank you.

Go through these, I have no ties to any sellers.

Yes, just the bare PCB, although I have the DACs and 7220s and probably most of the rest of the parts, I would just like to see how these guys designed it.
Thanks
Its interesting that the SAA7220 has an internal crystal oscillator, its designed to be used with an external 11.2896MHz XTAL. Here its being driven by the DIR9001 system clock output which will only be valid when its locked to an S/PDIF input signal. This might give the SAA7220 some hiccups as likely its designed to have a continuous 11MHz clock present.
Incidentally the schematic shows DIR9001 XTI as open whereas the DS says to connect to DGND when unused.
