Patent ID: 8687752

Claim:
A method for recovering bits from a serial bit stream signal having a given bit rate, comprising: receiving the serial bit stream signal concurrently at R different phase shifted samplers, where R is at least two; generating an M-phase signal, wherein M is at least an integer multiple of R, comprising M/R candidate sets of R phases, each candidate set of R phases comprising R phases equally spaced according to the inverse of the bit rate, selecting one of the M/R candidate sets of R phases as a selected R-phase sampling trigger comprising R consecutive trigger phases equally spaced according to the inverse of the bit rate; triggering the R phase shifted samplers, one at a time, each at a sampling time corresponding to one among the R consecutive trigger phases of the selected R-phase sampling trigger, to obtain at the R phase shifted samplers a block of R consecutive bits of the serial bit stream signal; and adjusting a phase of the R-phase sampling trigger relative to the serial bit stream by selecting another of the M/R candidate sets of R phases as the selected R-phase sampling trigger.
