ABSTRACT:
A method for controlling loop bandwidth of a phase locked loop is described. The method includes setting the loop bandwidth to a value, calculating at least one of a phase error and a frequency change that occur subsequent to any setting or adjusting of loop bandwidth, and adjusting the loop bandwidth based on at least one of the phase error and the frequency change.
