Abstract

The present invention is directed to circuits and communication. More specifically, a specific embodiment of the present invention provides a timing recovery device with two stages. The first stage generates a clock signal to sample the received waveform, and the second stage provides timing-jitter mitigation. The second stage includes a jitter mitigation circuit with coefficients a function of the instantaneous jitter estimate, in addition to a jitter estimation tracking loop consisting of an error generator, a timing error detector and a loop filter to compensate for timing jitter associated with the clock signal. There are other embodiments as well.
