Abstract
Embodiments of the present disclosure provide an apparatus including: a phase detector for detecting a write frequency of a deserializer and a read frequency of a serializer, such that the phase detector outputs a first code sequence in response to the write frequency being greater than the read frequency, or a second code sequence at the rotator input in response to the write frequency being less than the read frequency; and a phase rotator for receiving the first code sequence or the second code sequence from the phase rotator to transmit a pacing signal having the read frequency to the deserializer, wherein the pacing signal causes the read frequency to increase or decrease based on whether the read frequency is different from the write frequency.
