Hi Raj, I am summarizing some of points discussed in this thread: 1) The ADC12DJ3200 is compliant with the jesd204b Standard. It uses K28.5 as the comma character in the initial CGS sequence. The K28.7 character is used for marking frame boundaries (where necessary) when frame monitoring is used. 2) If your link comes up, it means that the K28.5 code you have selected in the transceiver wizard is accurate. I am assuming you have started with one of the existing reference designs, so this should already be set in the xci tile 3) If see noise, kindly check the error signals of the IP. You may be having signal integrity issues (or a corruption of the data if buffers have overflowed). For data integrity checks, kindly use the PRBS modes of the ADC to do an eye diagram check. 4) The LMFC pulse and SYSREF are not misaligned. As per the protocol, the LMFC boundary starts when a positive edge is detected on SYSREF. As a result, the LMFC pulse is delayed by a cycle, but it indicates the first cycle of the multiframe. regards, Ameet
