Abstract
Embodiments are disclosed for full-rate phase detection for a pulse amplitude modulation N (PAM-N) signal. The example method includes sampling an incoming signal in one or more sampling times. The example method further includes determining that an amplitude associated with a current sampling time is within an upper threshold and a lower threshold for each sampling time of the one or more sampling times. The example method further includes upon determining that the amplitude of the current sampling time is within the upper threshold and the lower threshold, determining an amplitude range associated with an immediately preceding sampling time and an amplitude range associated with an immediately subsequent sampling time. The example method further includes determining a transition status representing one of an upward transition, a downward transition, or no transition with respect to the current sampling time.
