CODEC interface

Here is the schematic for the TLV320AIC23B stereo audio CODEC interface that I mentioned in another thread:

I need to add stereo jacks and check the interface connections. It's actually intended for the XMOS XC kits, but it could easily be interfaced to a Propeller proto board.
I'm using a 6.144 MHz crystal, because I picked up 100 of them very cheaply on Ebay. The maximum sampling rate will be 48 kHz; I don't think that anyone wants to sample at 96 kHz, which would need a 12.288 MHz crystal. That would be useful for a software-defined radio.
