Hi members.

This is Ben.
Professor, please.

《The state》
　・Engineer   examines  DP139   for extension port   for   TV side.
　・SINK-TEST ID8-7:jitter-tolerance level.
        2.97Gbps and 2.2275Gbps   is passed.
        270Mbps is FAIL.
    It is necessary for this reason seek something.

《Q1》
　・Engineer　confirmed   oscillator by switching ON's swing.
     Engineer thinks the fail reason  transition time a stability of a swing.
     Do you have that this will be reason to the 270Mbps FAIL?

《Q2》
　・270Mbps　is near jitter frequency level. and would be margin less.
Do you have that this will be reason to the 270Mbps FAIL?

Best regard.
