My customer used AD9549 in holdover mode.

She wants to reduce the re-locking time of AD9549 when REF_IN was supplied again after that did not been for a while.


1. Could you recommend a method to reduce the re-locking time in AD9549 except for changing internal loop filter bandwidth or Icp ?

2. Please recommend a new device that can set holdover mode and a shorter re-locking time than AD9549.
