Abstract
In one embodiment, a method includes accessing a reference clock having a reference clock frequency and reference clock phase; generating an output clock having an output clock phase and output clock frequency that is a function of an analog control voltage setting and a frequency gain curve; fixing the analog control voltage setting to a predetermined voltage; selecting one of the frequency gain curves within a predetermined frequency range of the reference clock frequency at the analog control voltage setting; adjusting the analog control voltage setting to adjust the output clock frequency to be within another predetermined frequency range of the reference clock frequency; and adjusting the output clock phase to be within a predetermined phase range of an input data phase of the input data stream.
