Hello Yuan,

No, there is no influence internally between the different Rx Ports. However, there will be influence if the layout of the different Rx Input traces is not good enough, or if the PoC filter design is not good enough.

Hi Hamzeh,

it's clear, thank you, and one more question want to confirm, does port_pass (0x4D bit 1) matters? if customer ignore that, is that OK?

thank you

Hello Yuan,

Port_Pass if not used, it can be ignored.

However, configuring it on the right way and using it gives you the indication once the DES start receiving a valid video data.
