LMK04832: Approach Review

LMK04832: About LMK04832 nested Dual Loop ZDM

Hi，

As shown in the figure below, if the output clock edges of LMK need to be aligned with the reference, do you need to trigger SYNC EVENT？

If there are multiple parallel LMKs, the reference is 10MHz, and the configuration is as shown in the figure below. If the output clock edges of all LMKs need to be aligned with the reference, do you need to trigger SYNC EVENT？

Thanks！

    Yes, going through a SYNC event is needed whenever the output phase alignment is required.

    Yes, and setup 0-delay mode as well.

    Best,
