I have finalize to use DAC32RF82 for one of my application with LMFCHd mode (JESD)of 82121(2Tx) in DUC , but when i was trying to generate the test data pattern for this JESD mode for virtex7 it looks like xilinx JESD core doesn't support F=1 mode.Dose anyone tried this particular mode for virtex 7 and how ??
