LMX2572: SYNC and MASH_SEED function

Part Number: LMX2572
Other Parts Discussed in Thread: LMX2594,

Hi Teams,

I saw in https://e2e.ti.com/support/clock-timing-group/clock-and-timing/f/clock-timing-forum/1544486/lmx2594psevm-sync-and-mash_seed-function?tisearch=e2e-sitesearch&keymatch=LMX2820%25252525252525252520SYNC when LMX2594 SYNC is enabled, MASH_SEED will become unstable.

However, when I check the datasheet of LMX2572, the phase adjustment section did not say same thing as which in LMX2594 datasheet. I want to confirm will the LMX2572 have same problem or not. Since LMX2572 have the includeddivide too, I am afraid it is the same as LMX2594.

    Hi There,

    The channel divider and IncludedDivide are different in LMX2572, that monotonic characteristic in LMX2594 does not happen on LMX2572, at least, we haven't found a configuration can replicate this problem so far.
