20080266001 | DUAL REFERENCE PHASE TRACKING PHASE-LOCKED LOOP - A phase-locked loop circuit having a dual-reference input and a phase detector. The dual-reference input is configured to accept both a rising edge of an input clock having a first phase and a falling edge of the input clock having a second phase. The phase detector is coupled to the dual-reference input and is configured to produce a center phase signal based upon and centered in phase between the first and second phases. The phase detector is further configured with a feedback loop to adjust any tracking error and provide a tracking output signal.
