Abstract
An apparatus for recovering data and a method thereof are provided. The apparatus includes a reference clock generator which generates a reference clock, and a data recovering unit which detects an edge of received data and recovers the data using a time difference between a reference point of the reference clock and the detected edge.
Claims12
An apparatus for recovering data, the apparatus comprising:
- a reference clock generator which generates a reference clock;
- and
- a data recovering unit which detects an edge of received data and recovers the data using a time difference between a reference point of the reference clock and the detected edge,
- wherein the data recovering unit comprises:
- an edge detector which detects a rising edge and a falling edge of the received data,
- digital converters which set a start point of a half period of the reference clock as the reference point, compare the reference point with the rising edge or the falling edge of the received data, calculate a time difference with respect to the reference point, and output the calculated time difference as a digital value, and
- a data detector which recovers the received data using the digital value output in the unit of half period of the reference clock.
