DS90UB954-Q1: CSI-2 data rate

Part Number:DS90UB954-Q1

Hi, E2E members

We are planing to use some sensers that CSI-2 data rate are 184 ~ 506Mbps.

- Can we use the following setting DS90UB953 and DS90UB954?
DS90UB953-Q1 input : 184Mbps x 1 lane →　DS90UB954-Q1 output : 800Mbps x 1 lane
DS90UB953-Q1 input : 506Mbps x 1 lane →　DS90UB954-Q1 output : 800Mbps x 1 lane

1) Can the DS90UB954-Q1 use the setting of CSI-2 data rate of 800Mbps, regardless of CSI-2 data rate of DS90UB953-Q1 side?

2) Dose DS90UB954-Q1 have to change CSI-2 data rate of 400Mbps, if DS90UB953-Q1 input data rate below the 400Mbps?

Regards,
Nao
