Clock controller employing a discrete time control loop method for clocking data in an asynchronous channel

摘要

A digital data clock control loop for reconstructing the asynchronous data clock in a recording channel. The Discrete Time Control Loop (DTCL) implementation is suitable for monolithic digital embodiment and uses no analog components, providing stable operation at widely varying clock rates without hardware oscillators. The DTCL also can supply the clocking function to recover synchronous samples in an asynchronous data sampling system.
