DS90UB935-Q1: Ser output Data rate

Part Number: DS90UB935-Q1


Hi, Team,

How should I think about the output data rate?

The datasheet says the same equation and Table to calc data rate refer in Table 6 of the 935 datasheet.

If they use the pare with 954 using Sync mode with 25MHz Ref CLK, the data rate will be 4Gbps? and this case the CSI bandwidth will be 3.2Gbps...but the bandwidth is limited as 2.5Gbps...

please make me clear understanding...

Thanks,

Best regards,

Koh

    Hello Koh,

    935 forward channel operates at 4G or 2G depending on the configuration in table 6 of the datasheet, but the CSI-2 bandwidth is independent of the forward channel rate always. For 935 at 4G forward channel the CSI-2 max bandwidth is 2.528Gbps. In 2G mode the max bandwidth is 1.264Gbps. 

    Best Regards,

    Casey
