Unified time base for storage device data channel

Abstract

A method of clocking a data channel of a storage device includes generating a single time-base frequency signal, deriving from the single time-base frequency signal, using a plurality of frequency-modification techniques, a plurality of individual clock signals, each respective one of the individual clock signals being for clocking a respective one of reading, writing and servo functions of the data channel. When the storage device is a disk storage device having a rotational frequency, generating a single time-base frequency signal may include generating a time-base frequency signal based on the rotational frequency. Deviation of the single time-base frequency from the rotational frequency may be detected, and the deviation may be compensated for. Each technique of the frequency-modification techniques may be a digital frequency-modification technique, such as a digital timing recovery technique or a digital frequency division technique.
