This is part of the reason we used a 52 MHz clock for the public release of the OpenBTS GSM stack. It makes 13/48 MHz rational. We would have used 13 MHz, but the USRP-1 FPGA code fails to transmit for clock rates below about 48 MHz.
If you use the stock 64 MHz clock you will need a polyphase resampler for most telecom applications. You will also have wicked temperature drift problems.
