ADV7180 Analog video input trace impedance

Hi All,


I have an important query related to trace impedance of analog video input (CVBS) to the ADV7180 device present on my PCB. We have an RCA connector feeding the video input signal to the ADV7180 IC. Can we route this signal on PCB as analog trace with wider trace width (lower impedance )? Or do we strictly need to follow the 75 Ohms impedance guidelines? Also I am not sure if RCA connectors provide impedance matching.
