Serial interface circuit for adaptively supporting the serial interface of read/write channel circuits in a magnetic disk drive

摘要

A serial interface circuit for interfacing serial data between a control unit and a read/write channel circuit of a magnetic disk drive, includes a bit control data loading unit for loading the serial data to interface with the read/write channel circuit of a specified standard and the bit control data related to the transfer control signal of the serial data under the control of the control unit, and a serial interface control circuit for supplying the serial data to the read/write channel circuit by performing the bit conversion to adapt to the serial data, controlling the polarity and edge of the transfer control signal, and controlling the bit conversion by employing the loaded bit control data.
