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??
Lane Rate = Fs*M*N'*10/8*L, where Fs is the rate of the samples coming out of the JESD204B Rx (referred to as DataRate in the AD9152 DS) which equals DACRate / Interpolation Factor. Assuming N'=16 and with L=M=2, that leaves LR = DataRate*20. If symbol rate = DataRate, then LR = 5Gbps
Thanks, i have solved it.
