Is there any way to trim TMDS outputs driver current or drivers slope? (software or hardware).
I Designed a card which has a ESD protection and common mode chokes before connector. Traces are shorter than 4mm but I have still EMI problems. It seems I have to reduce output drive currents. Outputs has some overshoot and undershoot and it causes EMI.
All traces are routed properly on a controlled impedance PCB. I found so many registers which are documented as “Must be set to a suggested constant for proper operation”. Is there any way to manipulate output drivers to reduce this ringing phenomenon?
