Digital phase locked loop with integer channel mitigation |
摘要 |
An embodiment of the present invention provides a phase locked loop that operates on clock signals derived from an RF clock signal generated by the phase locked loop. A frequency reference input provides a reference clock. A controllable oscillator generates the RF clock signal with a plurality of phases. A switch is coupled to receive the RF clock, and is operative to select one of the plurality of phases. A phase detection circuit is coupled to the switch and is operable to receive a selected phase and to provide digital phase error samples indicative of a time difference between the reference clock and the selected phase.
