DS90UB954-Q1: Interface forum

Part Number: DS90UB954-Q1

Hi Team,

For DS90UB954&953 back channel, my customer draw a sample sketch for scope measured FPD-LINK III waveform like below shown ,  does this means back channel is enable and worked ?

If not, could you clarify what scope waveform look like on FPD-LINK line when back channel is worked? And is there any method to test the back channel link?
