Abstract:
A method for acquiring frequency and phase lock comprising:receiving a local oscillator signal;receiving an output clock signal;modifying the output clock signal according to a function to generate a modified output clock signal;causing a detector to compare the local oscillator signal with the modified output clock signal;adjusting the frequency of the output clock signal based on the comparison between the modified output clock signal and the local oscillator signal to generate an adjusted output clock signal having a frequency substantially equal to an expected data signal frequency;receiving a data signal having an actual data signal frequency substantially equal to the expected data signal frequency;causing the detector to compare the phase of the data signal with the phase of the adjusted output clock signal; andadjusting the adjusted output clock signal based on the comparison between the phase of the data signal with the phase of the adjusted output clock signal.
