ABSTRACT:
A transition detection, validation and memorization (TDVM) circuit detects the position of a transition in a stream of serially transmitted binary data (bits) that are over sampled and generates a control signal indicating which sampled signal represents the best data. The incoming data stream is over sampled by the n phases of a multiple phase clock signal. Then n over sampled signals are fed into the TDVM circuit which includes a first section for detecting the transition at the positions of two consecutive sampled signals according to a specific signal processing, a second section for validating the transition position, and a third section for memorizing the validated transition position and generating a control signal that is used to recover the data.
