DS90UB933-Q1: Can DS90UB933 support sensor OV2718 and 0V491？

Hi Team

We plan to use OV2718 and 0V491 sensor. we need to transmit 1920 X 384/60fps YUV422 8bit image. Can we use DS90UB933 to relize it.? We calculate the frequency as below, is that right ?

F=1920 X 384 X 2(YCB/YCR) X 60fps X 1.2 = 106Mhz > 100Mhz ？ Do this indicate 933 can not support the application ?

based on your calculation to the application, the PCLK 106MHz is over spec. in d/s of UB933, so it can't be used. the optional solution is:
1. select ub935/ub936
2. reducing the blanking ratio 20% or frame rate from 60fps to 50fps as one example.

Steven

Hi Steven
Another, is there other way to test the output signal quality of 933 or 935 except the eye diagram ?

no other solution except scope if just testing the serializer output signal quality.
