Clock relationship about jesd204 on ad9152-fmc-ebz

Hi,

     I am a bit confused about the clock of jesd204B.For  eaxmple, the jesd204 works in mode6, which means the parameter is lmfs=2221.My symbol rate is 250Mhz,  and I am doing 2-phase shaping filtering.In the jesd204B  Will my sample clock be 250Mhz or 500Mhz, and the corresponding bit clock(lane rate) is 5Ghz or 10Ghz,What should be datarate??

                                                                                                          Thanks
