| titleOfInvention | Clock and data recovery circuit in data communication system |
| abstract | As a simple structure, the present invention relates to a clock and data recovery circuit capable of accurately recovering a clock by simultaneously detecting phase and frequency variations of input data. The phase / frequency detector detects phase and frequency errors between the input data and the clock by using the restored first clock and the third clock having a phase difference of 90 ° from the first clock, and accordingly, the data lag signal and the data read. Generate a signal. The charge pump increases or decreases the amount of charge according to the difference between the data lag signal section and the data read signal section output from the phase / frequency detector, and the loop filter removes noise components from the output of the charge pump. The voltage controlled oscillator increases or decreases the period of the clock to be restored according to the output of the loop filter, and the double edge trigger D flip-flop readjusts the input data by the positive first clock and the negative first clock which are recovered from the voltage controlled oscillator and output.
