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.
