Part Number: SN65DPHY440SS

Hi, team:

Hope everything going well with you.

My customer is choosing CSI re-timer and have some questions about SN65DPHY440SS, could you help it?

1) if use 1 lane ,600Mbps and cable 1M loss 3dB, does one SNDPHY440SS could support, is their any more suitable device could recommend?

2) In addition if use SN65DPHY440SS for 1 lane CSI , should I use DA0P or DA1P？

Hope to get your reply, thank you!

Hi,

Reference to table 1, max equalization is 5dB at 750MHz (1.5Gbps), so I do not see an issue with supporting 3dB loss at 600Mbps.

For CSI one lane, please use lane DA1P/N.

Thanks

David

Hi，David：

Could you help review the SN65DPHY440SS schematic？ and could you give some suggestion about EQ/SCL, ERC/SDA,RRE_CFG1,VSDJ_CFG0?

Hi,

I do not see an issue with the schematic. The EQ/SCL, ERC/SDA,RRE_CFG1,VSDJ_CFG0 have to be tuned depending on the input and output channel characteristic.

Thanks
