Abstract
A semiconductor integrated circuit includes a clock generator which generates a first clock, a test data generator which modulates a phase of the first clock, and generates test data to which jitter is added by using the modulated clock, a data extractor which samples the test data and extracts recovery data, and a detector which detects an error of the recovery data.
