Dear,
The FMC30RF does not implement a PSK demodulator. The demodulator chip on the FMC30RF, the TRF371125 is a I/Q demodulator which means that it performs down conversion, and generates a complex output from the spectral input. There is no hardware feed-back that allows you to adapt the ADC sample clock (nor the LO) to the received PSK signal. You will have to perform your clock recovery in the digital domain, using DSP software or DSP inside the FPGA.
