exceptions:
⢠Write 1âb1 to 4/5.32768.2 instead of 4/5.32768.1.
⢠Write 1âb1 to 4/5.32769.2 instead of 4/5.32769.1.
⢠Write 1âb0 to 4/5.32809.15 instead of 1âb1.
⢠1000Base-X Based High/Mixed/Low Frequency Test Pattern:
â Device Pin Setting(s):
⢠Ensure ST primary input pin is high.
⢠Ensure CODE primary input pin is low.
â Reset Device:
⢠Issue a hard or soft reset (RST_N asserted âor- Write 1 to 0.15)
â Select single ended or differential REFCLK input:
⢠If Single Ended REFCLK used - Write 2âb01 to 4/5.37120.15:14
⢠If Differential REFCLK used â Write 2âb00 to 4/5.37120.15:14
â Select SERDES TX Reference Clock Input:
⢠If Single Ended REFCLK used - Write 2âb10 to 4/5.37120.11:10
⢠If Differential REFCLK used â Write 2âb11 to 4/5.37120.11:10
â Select SERDES RX Reference Clock Input:
⢠If Single Ended REFCLK used - Write 2âb10 to 4/5.37120.9:8
⢠If Differential REFCLK used â Write 2âb11 to 4/5.37120.9:8
â Disable Comma Detection:
⢠Write 1âb0 to 17.7
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
â Select Test Pattern:
⢠If High Frequency Pattern is desired:
â Write 3âb000 to 16.2:0
⢠If Low Frequency Pattern is desired:
â Write 3âb001 to 16.2:0
⢠If Mixed Frequency Pattern is desired:
â Write 3âb010 to 16.2:0
â Enable Test Pattern Generation:
⢠Write 1âb1 to 16.4
â Clear Counters:
⢠Read 22.15:0 and discard the value.
â Enable Test Pattern Verification:
⢠Write 1âb1 to 16.3
â Verify Test In Progress:
⢠Poll 21.1 asserted.
â The pattern verification is now in progress.
â Verify Error Free Operation (as many times as desired during the duration of the test period):
⢠Read 22.15:0, and verify 16âh0000 is read to confirm error free operation.
⢠1000Base-X Based Continuous Random Pattern (CRPAT) Long/Short Test Pattern:
â Device Pin Setting(s):
