DS90UB953-Q1: Data rate calculation

Tool/software:

Hi,

as per datrasheet ds90ub953 max csi Bw is 832mbps per lane.

so for our device Camera resolution 1920*1536*60*16*(25%overhead)= 885mbps per lane which is above capabiltiy of the ser 953.

Is it neccesaary to take overhead 25%(15% blanking +10%csi) ?

how to make this system compatible with 953 serializer.

Hello Atul,

The 25% is an estimate only. To get an accurate number I suggest to contact your image sensor vendor directly and inquire about the CSI-2 lane rate when operating the sensor in your desired mode. They will be able to tell you the exact number and as long as it is < 832Mbps/lane, then it can be supported by 953

Best Regards,

Casey

Atul,

There is no relationship to FPD here. All you need to confirm is if the sensor lane rate is < 832Mbps

Atul,

4.16Gbps is the FPD-Link forward channel signaling speed
