LMK04808

Software lock detection possible, Is there a status reg that can be read to determine the lock state of the PLL's and the input status of the ref clock inputs.  Would like this for test vs an external circuit.

    Hello Stephen,


    On the LMK04808 there is no software bit to read back lock detect status.  The LMK04828 does have this feature for PLL lock detect.

    For reference input clock, we do have LOS (loss of signal detect) on both devices.  It is recommended to set MOS input mode on the clock inputs to use the LOS detect functionality.  The LMK04808 does not have readback for LOS.  LMK04828 can readback LOS.
