Dear Sir,

we designed DS90UB960 and DS90UB953.

We need to mux CSI-2 data of Sensor0, Sensor1. and mux CSI-2 data Sensor 2 and sensor3.

we are using CSI-2 2 lanes data of each sensor.

DS90UB960 support mux CSI-2 data input and CSI TX can support as below structure?

If possible. how to set the register of DS90UB960. please let me know the guide.

Yes, 960 can support this function, you can set:

1. forwarding FPD-Link port0/port1 to CSI2 port0, forwarding FPD-Link port2/3 to CSI2 port1. reg. setting of 960: 0x20

2. set CSI2 port lane number in reg.: 0x33.

best regards,

Steven

Hello,

I just check the reg., the 0x20 should be set as 0x0C.

also, the reg. 0x73/74/75/76 (04 38 0f 00) is correct, it mapped the input video in RX1 (0x4c = 0x12) is 1920x1080 (yuv422).

regards,

Steven
