Abstract: A device includes a physical medium attachment (PMA), a physical coding sublayer (PCS), a phase detector, and an oscillator. The PMA receives data at a first speed and overclocks the received data to a second speed, wherein the second speed is higher than the first speed. The PCS receives the data at the second speed. The phase detector receives another data from the PCS wherein the another data is based on the received data at the second speed or the phase detector is configured to receive the data at the second speed directly from the PMA. The phase detector adjusts a phase based on bit transitions. The oscillator is coupled to the phase detector and generates a reference clock signal wherein a phase of the reference clock is adjusted by the phase detector. The oscillator clocks the PMA based on the adjusted clock.
