⢠If Single Ended REFCLK used â Write 2âb10 to 37120.11:10
⢠If Differential REFCLK used â Write 2âb11 to 37120.11:10
â Select SERDES RX Reference Clock Input:
⢠If Single Ended REFCLK used â Write 2âb10 to 37120.9:8
⢠If Differential REFCLK used â Write 2âb11 to 37120.9:8
â Ensure a legal reference clock operation frequency is selected based on Appendix A, and provision
control settings accordingly. It is also possible to use the Jitter Cleaner during these tests, and the
user should consult Appendix A for further Jitter Cleaner provisioning details.
â Issue Datapath Reset:
⢠Write 1âb1 to 16.11
⢠Write 1âb0, then 1'b1, followed by 1'b0 to 37636.14
â GPO1 contains a real time output that when high indicates if the input PRBS pattern on TDÃ1/RDÃ1
is errored.
â GPO0 contains a real time output that when high indicates if the input PRBS pattern on TDÃ0/RDÃ0
is errored.
⢠SERDES Macro 27-1/223-1 PRBS Register Based Testing
