DS90UB953-Q1: 2-Lane Pin Configuration

Kevin Schmidgall

Part Number: DS90UB953-Q1

Hi,

I just want to confirm that when you set CSI_LANE_SEL to 2-lane configuration you must use CSI_D0 and CSI_D1. Or is it possible to use any of the CSI lanes as the 2-lanes.

Or is there a way to configure which lanes are used in the 2-lane configuration?

Regards,

Kevin

Hi Kevin,

You will need to use lanes 0 and 1 for 2-lane configuration. The 953 does not support lane swapping or remapping.

Thanks Cindy!

Do any of our serializers and deserializers allow lane swapping or remapping?

Hi Kevin,

Currently none of our devices have this feature. The only type of CSI-2 lane swap that is supported is a polarity swap. This can be configured by configuring Register 0x21 in the serializer.
