Digital Modem Codec and SDR

I've be looking at several platforms to do DSP work in relation to a SDR and digital modems.  I have a xmos demo board and some AVR32 items laying around which I needed nice DAC/ADC to interface with.  The TLV320AIC23 is a nice inexpensive codec.  I built a small prototype board to use the chip in development products and later I'll turn this into a module that can just be plugged in to various projects.  This board can be used with a small MCU 16-32 bit to do APRS, GSMK (DSTAR), P25 and various other digital demod/mod.  The board breaks of all of the TLV320 channels for both input and output.
