请看下面e2e工程师的回复。

CSITX is transmitter, used to send out the data from SoC. if there is any CSI based display, then it can be used for the display. 

In the above list, we also need to understand the format support require.

For camera, it requires total 520MP/s, even if we use yuv422 data for the capture, it would require around 8.5Gbps speed, this should be possible using two CSIRX blocks.

For display, we need to merge two display side-by-side or top-bottom, and then we can send it via CSITX. The other option is to use two output interfaces like DP + CSITX.

Hi, Shine, 关于速率，假设选用2路FPD link输入，一路CSI输出的Deserializer，FPD link的速率和CSI的速率是什么样的关系？

CSI的速率是2路FPD link速率相加吗？还是CSI可以分别适配FPD link的速率？如下图：

谢谢回复。

已跟进！

Since CSI output is for both LinkA and LinkB, CSI rate should atleast be LinkA rate + LinkB rate. But this question is related to TDA device, i would suggest to ask this question on SERDES forum.

不客气~
