trouble shooting AD9675 JESD204B data read zero for intermittent

1.Main IC: XC7A100T(FPGA) + AD9675
2.Refclk: buffer IC drive the same 125MHz clock to both ADC & FPGA(GTP refclk)
3.Parameter:
    clock in 125MHz
    L=4
    M=8
    F=4
    K=8
    enable RF decimator


4.Parameter setting is same with the IP core.
