Patent ID: 6990161

Claim:
A phase selection mechanism for facilitating the sampling of data, said phase selection mechanism comprising: an arrangement for interfacing with a transmitter clock; an arrangement for interfacing with at least one receiver clock; a phase sampler which ascertains the position of the transmitter clock with respect to the at least one receiver clock, whereby a suitable receiver clock for sampling data is ascertainable; a phase selector adapted to generate a phase selection signal; and a plurality of multiplexers which create clock signals; wherein a first one of said multiplexers is adapted to create a first clock signal; wherein a second one of said multiplexers is adapted to create a second clock signal; wherein a third one of said multiplexers is adapted to create a third clock signal; wherein said phase selector being adapted to control the phase of the clock signals created by said multiplexers, wherein said phase sampler comprises: an arrangement for generating a first phase sample, based on said second clock signal; an arrangement for generating a second phase sample, based an said third clock signal; and an arrangement for combining the first and second phase samples to generate an output; and an arrangement for producing a phase sample signal based on the output of said combining arrangement and on said third clock signal.
