Abstract: A phase-locked loop circuit includes phase detection circuitry to generate a first control signal based on a phase comparison between first and second periodic signals. An oscillator circuit causes a frequency of a third periodic signal to vary based on the first control signal. A frequency divider circuit divides the frequency of the third periodic signal by a frequency division value to generate a frequency of the second periodic signal. A delta sigma modulator circuit controls the frequency division value based on second control signals. First storage circuits store the second control signals based on third control signals in response to a fourth periodic signal. A second storage circuit stores an output signal based on a fourth control signal. The fourth periodic signal is generated based on the output signal of the second storage circuit.

Abstract: Techniques for sampling input data streams with an integrated circuit (IC) are provided. The technique includes receiving a first input stream at a first operating rate. The first input stream is transmitted to a plurality of subsequent transceiver channels on the IC. The first input stream is then sampled at a second operating rate at each of the plurality of subsequent transceiver channels with each of the plurality of subsequent transceiver channels outputting a data stream at the second operating rate. The data stream from each of the plurality of subsequent transceiver channels is adjusted. A data stream from one of the plurality of subsequent transceiver channels is selected as an output of the IC.

Abstract: A demultiplexer circuit separates input data having different data rates into output data. A phase-locked loop circuit generates first clock signals having average frequencies that are based on a frequency of a second clock signal times a fractional, non-integer number. A serializer circuit serializes a set of the output data to generate serial data signals in response to one of the first clock signals generated by the phase-locked loop circuit.
