Common Failures/Issues

•  Transmission path at 5.4Gbps

•  Hosts have the biggest challenge due to path length

•  At 5.4Gbps losses due to FR4 can hurt

•  Tuning for power consumption makes margins even tighter

•  Aux channel SQ testing

•  Until now not much has been done here and many designs will have

some signal quality issues

•  Causes interop issues, especially with long cables)

•  Baseband/link layer support for testing

•  This is a HUGE issue. Many products are NOT testable due to no hw or

sw support for test modes and/or aux channel controllers.
