Systems and methods for timing control in a data processing system

摘要

The present inventions are related to systems and methods for data processing, and more particularly to systems and methods for synchronizing operations in a data storage system.

1. A method for preparing data for a storage write, the method comprising:
providing a synchronizing clock and a data stream from a read channel circuit to a preamplifier circuit at a first phase offset between the synchronizing clock and the data stream; changing the first phase offset to a second phase offset a first distance from the first phase offset; identifying a possible setup failure of a register in the preamplifier circuit corresponding to the second phase offset; changing to a third phase offset a second distance from the first phase offset; identifying a possible hold failure of the register in the preamplifier circuit corresponding to the third phase offset; calculating a default clock phase offset between the second phase offset and the third phase offset; and applying the default clock phase offset to a clock of the read channel circuit to yield the synchronizing clock of the preamplifier circuit.
