I am using fmcomms1. I am trying to transmit my own wave, however at the receiving side the clock of AD9643 adc_clk seems that introduce sometimes phase changes. I can notice this one in my waveform that I am receiving. See the attached figure where the yellow line is set. There is an phase change which shouldn't be there. Also the clock (adc_clk) is not with constant pulse shape, sometimes the pulse shape is smaller.
I am using an adc_clk of 64 MHz my chipscope clock is 200 MHz.
Any idea how to fix this!?
