DS90UB635-Q1: Serializer capable of connecting a plurality of cameras

Hi Nishie, 

Each FPD-Link serializer supports one CSI-2 interface with one CSI clock input and maximum of 4 data lanes. Based on the application diagram, this use case would not be supported as it requires two CSI-2 interfaces on the serializer. In order to achieve this application of two input camera streams to one serializer we recommend combining the two CSI-2 interfaces into one source via an ISP or other component. 

Best,

Zoe
