Part Number: SN75DPHY440SS

Hi Team,

My customer need 6 CSI@1lane retimer solution. Do we have solution can support multi-port CSI?

Or, we just can use SN75DPHY440SS*6 for customer's application?

Best regards,

Unfortunately we do not have a solution that can support 6 CSI lanes. You can not use 6 DPHY440 since the part-to-part skew is not guaranteed.

Thanks

Hi David,

Thanks for your reply.

I am not sure my question cause you misunderstand.

Customer's need are 1 lane CSI *6. Your reply look like mean that 6 lane CSI *1. If I misunderstand, please correct me. Thanks.

Best regards,

Hardy

You are looking for using 6 DPHY440, and each of them only support 1 CSI lane?

Thanks

Hi David,

Yes, if we have a solution can support 6 ports with every 1CSI lane, that would be better.

Best regards,

Unfortunately you can not use 6 DPHY440 in parallel since the part-to-part skew is not guaranteed.

Thanks
