发明名称 Information processing apparatus
摘要 An information processing apparatus capable of reducing propagation delay differences and error factors, capable of realizing high precision binarization control, and accordingly capable of realizing high precision reproduction, including a comparator for converting an RF signal to a binarized signal; an edge position measurement unit for measuring the edge position of the binarized signal in a time axis by multi-phase clocks; a jitter measurement unit for measuring the amount of jitter based on the edge position information; an edge interval measurement unit for measuring the edge interval length based on the edge position information; a propagation delay difference control amount calculation unit for controlling propagation delay amount between an input and an output of the comparator by injecting a slice level voltage of the comparator through a DAC based on the measured amount of jitter and edge interval length; and a channel data discrimination unit for reproducing the data corresponding to the channel clock based on the edge position information.
