DS90UB953-Q1: CSI_CLK

Part Number: DS90UB953-Q1

Hi Sir 

We would like to check CSI_CLK rate max and min value of DS90UB953 an DS90UB935

1. OV7261 / 1lane MIPI / 640x480 / 100f and "PCLK=60MHz"

2. OV2311 / 2Lane MIPI / 1600x1300 / 60f and "PCLK=160MHz"

Could DS90UB935 support these two sensor ?

    Hello Kai,

    For 935/953, the data rate is not directly dependent on the PCLK because you must consider the data type (bits per pixel) and CSI-2 overhead. Please consult your image sensor vendor for CSI-2 lane speeds in your desired mode of operation and note that 953 can support up to 832Mbps/lane. 935 can support up to 632Mbps/lane. 

    Best Regards,

    Casey
