Abstract
In one embodiment, an apparatus including a phase detector unit to determine a phase difference between a reference clock signal and a feedback clock signal. The apparatus further includes a controller unit to generate a delay signal based on the phase difference. The apparatus further includes a set of voltage-controlled delay lines to generate phase outputs based on the delay signal, where the phase outputs are provided by the apparatus to a clock generator unit to generate an oversampled clock signal for data recovery by a receiver.
