Abstract

See full text

A reference voltage generator generates a reference voltage at the time of sampling a received input signal. A sampling time controller detects a change in the reference voltage. When the reference voltage rises to a determined threshold, the sampling time controller determines that sampling is completed, and generates a sampling clock in which sampling time is controlled on the basis of an external clock.
