Analysis of the effects of pulse shape and width on the retiming properties of a 3R regenerator

The jitter (retiming) transfer function of the 3R regenerator in the presence of the recovered clock signal was investigated based on a newly developed numerical model. The effects of data signal jitter and pulse shape, recovered clock signal jitter and FWHM of control signal pulses on the timing jitter of the retimed data signal is investigated. The jitter performance of a 3R regenerator significantly improves for flat-top data signal pulses and decreasing control signal pulse width.
