Part Number: DAC38RF89

Hi, Team

My customer wants to do a PRBS31 test, by using the checker in DAC38RF89 to check if the physical layer is good.

They can make the DAC38RF89 work well if FPGA output tone.

But they don't know how to allocate the PRBS31 data into the 8 lane of JESD204b.

From this application note of test mode, Table 3, there is  description about what data is loaded in I/Q channel for a specific short pattern.

Customer would like to know if they want to do a PRBS31, is there any guide about the specific channel data need to match for checker?
