Dear Team,
My customer get the failed item on HF 1-9 as below figure.
In the schematic, there is only a common mode choke between DP159 and HDMI connector.
Where is the location that cause the impedance drop? Could DP159 improve the test result?
Data1 Fail. Impedance lower than 85 ohm limit.
Data2 Fail. The impedance lower than 85 ohm limit and higher than 115 ohm limit.
Thank you.
Regards,
Jim
