Part Number: LMK5B33216

Tool/software:

Hi expert,

If the LMK5B33216 can support <10ps phase adjustment step and configure delay time for every output channels? And how to configure? Thanks.

Best Regards,

Ryker

    Hi Ryker,

    Do you need phase adjustment applied to all outputs at once?

    If so, there is the DPLL DCO or APLL DCO features which can apply frequency and phase adjustments by < 1 ppt.

    Alternatively, there are analog delays that can be applied to each output channel but the adjustment is more coarse (around 12 ps), as defined in the datasheet below.

    Does your design require phase determinism which means the input and output phase relation is deterministic at start-up?

    Regards,
