3.4.1 Test Summary

TX presets: BRCM, J16 meets the PCI Express 4.0 requirement.

ISI eye openings:

  • BRCM meets all preset requirements
  • J16 is able to pass P06, P07, P08, and P09 only. Technically, at least one preset needs to pass to claim compatibility

Figure 3-3 and Figure 3-4 illustrate the test reports for preset and ISI eye opening tests.
