SN75DPHY440SS: Supported data rate for MIPI-CSI

Rohanth Prabhakaran

Part Number: SN75DPHY440SS

Dear Sir,

I saw the that SN75DPHY440SS can support 4 lanes at 1.5Gbps, I want to know that 1.5Gbps is equally divided for all the four lanes like maximum of 375Mbps per lane.

I have 2 lane MIPI-CSI, which has 700Mbps for each lane so the over all data rate is 1.4Gbps. I want to know that I can use this IC for my 2 lane camera with one clock lane.

Thank you

Hi,

The 1.5Gbps is not the total bandwidth, it is per each lane. So the DPHY440 can support 700Mbps data rate.

Please note that lane 0 supports bi-directional communication. For MIPI-CSI 2 lane, I would recommend do not use lane 0, use lane 1, 2, or 3.

Thanks

David
