Part Number: DS90UB954-Q1

Hi Sir 

Our Sensor MIPI clock output is 46MHz ,but DS90UB954 output clock is 200Mhz

Have any register can set freq down to 46MHz ?

    Hello Kai,

    The 954 outputs CSI-2 at discrete rates as defined by the CSI_PLL_CTL register. The lowest rate is 200MHz (400Mbps) and it does not need to match the input data rate for the sensor. It just needs to be >= to the input data rate to avoid buffer overflow. 

    Best Regards,

    Casey
