DAC38RF89: PRBS31 test on JESD204B

Part Number: DAC38RF89

I want to do prbs31 test on JESD204B interface. FPGA is transmitter, DAC38RF89 is receiver.

But the Xilinx JESD204 IPcore cannot  sent prbs31 test pattern, how can I do the test?

If use Xilinx IBERT debug tool to send prbs pattern, can DAC38RF89 check?

    Hi,

    The PRBS31 testing is a physical layer testing. The Xilinx IP core on the Physical layer front should support PRBS31

    The PRBS31 generated on the JESD204 IP core will go through 8b/10b coding, which is not the phyiscal layer testing supported by the DAC38RF89 SerDes Phyiscal layer receiver.
