    Hello Lawrence,
    PDO# terminal has exactly the same functionality in both devices.
    With no input, the device will output the free-running PLL on ODCK. With no input, the state of the control and data output signals is unknown. Noise on the differential data inputs can be decoded as random data and therefore appears to change the output as the free-running PLL output changes.
    To avoid this situation SCDT pin should be connected to PDO.

    Regards
