Method And Apparatus For Achieving Fast Phase Settling In A Phase Locked Loop
US Patent:
5754607, May 19, 1998
Filed:
May 10, 1995
Appl. No.:
8/439091
Inventors:
William E. Powell - Raleigh NC
David T. Hayes - Raleigh NC
David T. Hayes - Raleigh NC
Assignee:
Alcatel Network Systems, Inc. - Richardson TX
International Classification:
H03D 324
US Classification:
375373
Abstract:
A method and an apparatus are provided to achieve fast phase settling when a reference signal for a phase locked loop changes from a first frequency to a second frequency, such as during holdover recovery in a synchronous optical network. The present method acquires the second frequency with a phase locked loop (24). After the frequency is acquired, the integral register (39) of the phase locked loop (24) is loaded with the contents of the output frequency register (34) of the phase locked loop (24). The phase detector (28) of the phase locked loop (24) is then realigned to the reference signal.
