| titleOfInvention | Data recovery circuit in high frequency system |
| abstract | BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data recovery circuit in a high frequency system, and aims to recover the input data into data having a more accurate waveform after canceling phase and frequency errors by combining input data and a restored clock. The data recovery circuit in the high frequency system according to the present invention for achieving the above object is a phase frequency detection unit for generating a charge up signal and a charge down signal after combining the input data and the recovered clock signal to cancel the phase and frequency error ; A charge pump configured to perform a current pumping operation according to whether the charge up signal and the charge down signal are higher or lower than a reference voltage; A loop filter receiving the output signal of the charge pump and outputting a DC control voltage Vdc; A VCO receiving a DC control voltage output from the loop filter and detecting a frequency and a phase proportional to or inversely proportional to the DC control voltage, and generating a plurality of recovered clock signals having different phases; And a data recovery unit configured to receive the input data and the plurality of restored clock signals and restore the input data to data having a more accurate waveform. |
