A method and circuit for measuring a statistical value of jitter for a data signal having a data rate f<SUB>D</SUB>, comprises digitally sampling the data signal at a sampling rate, f<SUB>S</SUB>, to produce sampled logic values, where f<SUB>D</SUB>/f<SUB>S </SUB>is a predetermined non-integer ratio; and analyzing the sampled values to deduce a statistical value of the jitter.
