Abstract
A storage device configured to communicate with a host according to a serial communication standard. The storage device includes a receiver configured to receive host data from the host; a clock data recovery circuit configured to determine a first frequency of host data transmitted by a host; a phase locked loop configured to generate a local phase corresponding to a local clock signal; a frequency offset calculator configured to generate a frequency offset corresponding to the first frequency and a second frequency of the local clock signal; an accumulator configured to generate a phase offset corresponding to a difference between the local phase and a phase of the host data; an interpolator configured to generate a compensated local clock signal using the phase offset and the local phase; and a transmitter configured to transmit device data to the host using the compensated local clock signal.
