Document Type and Number:
WIPO Patent Application WO/2017/095186
Kind Code:
A1
Abstract:
Disclosed is a clock and data recovery apparatus. Specifically, the clock and data recovery apparatus according to an embodiment of the present invention comprises: a linear phase detector for comparing a phase difference and a frequency difference between a received data signal and a recovered clock signal and outputting an up signal and a down signal corresponding to the comparison value; a charge pump for outputting a current corresponding to the up signal and the down signal inputted from the linear phase detector; a loop filter for outputting a VCO adjustment voltage corresponding to the current inputted from the charge pump; a voltage controlled oscillator for recovering a clock signal having a frequency and a phase corresponding to the VCO adjustment voltage outputted from the loop filter, and outputting the recovered clock signal to the linear phase detector; and a reset circuit for initializing the VCO adjustment voltage to a preset reference voltage.
