    Hello,

    The Power over coax filter shown on DS90UB934-Q1 provides higher impedance across wider frequency range and also can be acceptable for DS90UB933-Q1. For the image sensor/DS90UB933-Q1 side there is alternative filter shown for smaller size.
    Please refer to and follow recommended application diagram in the datasheets.

    Regards,
