Hi, Team,

I am looking for the soution such as Repeater connection with 953-954.

Is it possible to configure as following?

which is 4-Lane to 2-Lane to 4-Lane communication..

Sensor (CSI2 4-Lane) => 953 <===> 954 Replicate mode (CSI2 2-Lane) => 953 <===> 954 (CSI2 4-Lane)

(CSI2 2-Lane) => 953 <===> 954 (CSI2 4-Lane)

Thanks,

Best regards,

Koh

Koh,
yes, it can work. but pls make sure the right 954's clocking is not less than the left 954's clock freq. (+/-50ppm variation)

regards,
Steven

Steven,

Thanks for the reply.

Let me double check, It means it can work that we make sure right settings for Output lane count register.
And we don't need to care about the data packing, am I right?

(I mean the format of Sensor output and 954 4-lane output are the same?)

Sensor (CSI2 4-Lane) => 953 <===> 954 Replicate mode (CSI2 2-Lane) => 953 <===> 954 (CSI2 4-Lane)

(CSI2 2-Lane) => 953 <===> 954 (CSI2 4-Lane)

thanks again,
Best regards,
Koh

Hello,

it does not matter the data lane number, but please make sure the data lane total bandwidth is enough for the video signals.

best regards,

Steven
