LMX2594: LMK04832 and LMX2594 Phase Shift With Sync

Part Number: LMX2594
Other Parts Discussed in Thread: LMK04832

Hello TI,

We are using the LMK04832 Clock Conditioner to give Clocks and SYSREF(Sync Pulse) to 5 LMX2594 PLLs.

Our Operation Range is from 30MHz to 8GHz.

The LMK04832 is Outputing 25MHz Clock and 0.5MHz SYSREF from a 200MHz Clock.

When the PLLs Lock to 50MHz... They are Sync but when we Apply MASH_SEED of 500(3.5 Degrees).
The PLLs Behavior is Unstable. 

can you please suggest some solutions??
we are using a Fosc of 25MHz to satisfy the N Value of Greater than 45 with a 2nd Order Modulator.
