SN65DPHY440SS: 2.5Gbps retimer

Part Number: SN65DPHY440SS
Other Parts Discussed in Thread: SN75DPHY440SS

Hello Guys,

Upon looking at TI's Retimer portfolio with MIPI CSI2/DSI protocol, they only have two namely SN65DPHY440SS and SN75DPHY440SS.

Do we have something in development that is a a MIPI CSI2/DSI DPHY1.2 retimer which has same temperature grade as SN65DPHY440SS but able to support 2.5Gbps?

Thanks in advance!

Unfortunately, we currently do not have a MIPI retimer in development that can support 2.5G.

Thanks

Hello David,

Thank you for the confirmation. Just a follow-up inquiry though.

Just curious for 1.5Gbps what is the maximum channel extension which can be realized after the retimer.

The customer is hoping it is not just 1 inch as shown in eval board.

Thanks!

The placement of the repeater is a system choice. If one would like to take use of DPHY440’s RX EQ capability for ISI compensation he may want DPHY440 close to TX. So the 1in placement is to maximum the RX EQ and skew compensation as much as possible.

Thanks

David
