ADV7610 RGB output - 50 ohm impedance

Question asked by DenisDarmon on Sep 13, 2016

Most video devices with RGB output recommend using 50 ohm impendance.

1) If using 50-ohm series resistor on each signal line, do the traces still need to be 50-ohm impedance controlled on PCB?

2) And if so does the impedance need to be controlled on both sides of the resistor (from ADV7610 to resistor and from resistor display/connector)?

3) Can the series resistors be removed if the PCB trace impedance is controlled at 50-ohm?

 

Thanks.
