Abstract: A phase detector includes a first clock driver comprising a first LC tank. The first clock driver provides a strobe to a plurality of flip-flops associated with sampled data being received by the phase detector. The second clock driver includes a second LC tank. The second clock driver provides a strobe to a plurality of flip-flops associated with sampling the phase error of the phase detector. The first and second LC tanks have different adjustable center frequencies and experience a programmable delay between the outputs of the first and second clock drivers so as to determine the data sampling phase of the phase detector.
