Part Number: AFE7950EVM
Other Parts Discussed in Thread: AFE7950,

Hello,

I'm using the AFE7950EVM and Xinlinx VCU128 FPGA. When I  use the Latte to configue the AFE7950, there is an error which is in the attenched picture.

could you please tell me why the CS state is right but the FS state is wrong, The LMFS is 4421 for both rx/tx.

    Hi Wei,

    One thing to check is that the SYNC Pins are routed correctly on the FPGA side. If set to LVDS, does the FPGA have the same connections? Do you see the SYNC pin go low then back to high? Another thing to check is that the LMFS parameters on the FPGA side match what is programmed on the AFE side.
