초록
A clock and data recovery apparatus reduces current consumption and enables easy integration. The inventive apparatus includes a first loop including a frequency/phase detection unit, a first charge pump unit, a multiplexing unit, a filtering unit, and a voltage controlled oscillator unit operating at a speed � as fast as that of received data; a second loop having a phase detection unit operating at a speed � as fast as a speed of received data, a second charge pump unit suitable for the phase detection unit, the multiplexing unit, the filtering unit, and the voltage controlled oscillator unit; a frequency lock detection unit for judging whether a frequency of a feedback clock signal falls within a desired frequency range; and a data recovery unit for recovering data from received da
