AD_FMCOMMS1 synchronization problem with 30MHz clock

I have two AD_FMCOMMS1 boards, and i´m trying to synchronize them. I made a  test where i find out that the 30MHz clock from the FPGA to AD9548, is not working properly, at least that what it seems. I´m using an ML605 and i put one AD_FMCOMMS1 in LPC and the other one in HPC, then i forced the 30MHz clock to be driven for the two boards, and connect the tx from one board to the rx from the other board and the clok rate from dac and adc are diferent in the two boards!
