LMK03328: Sync Query

PRAHLAD Supeda

Part Number: LMK03328


 My customer finalized to use LMK03328. Can unused outputs of Clock Generator be disconnected?
Can 4 outputs of PLL2 be used to generate same frequency with sync between them and to have different frequency at one output of other PLL1 for diffrent application?

    Hi,

    If the output buffer is disabled, the unused output can be left floating.

    Yes, if the 4 output frequencies are the same and are generated by the same PLL, the phase should be in sync. It is also possible to sync those outputs with a different frequency output from a different PLL using the output sync feature by toggling GPIO0 (SYNC pin). See section 10.4.17 on page 49 of the datasheet for a description of this feature.

    Regards,
