A clock and data recovery circuit injects a noise waveform into the control loop to offset the data sampling point artificially in order to induce errors. The amplitude of the injected waveform can be varied to ascertain the effect on the bit error rate (BER) so as to be able to evaluate the temporal noise margin.
