Abstract: Embodiments of phase-generation circuitry and methods for generating a multiphase signal with duty-cycle correction are generally described herein. The phase-generation circuitry may include a plurality of controllable delay stages arranged in series and phase detector circuitry. Each delay stage may be configured to phase shift a differential signal based on a control signal. The phase detector circuitry may be configured to generate the control signal based on a first time difference and a second time difference. The first time difference may be a time difference between rising edges of a first component of the differential signal and a second component of a phase-shifted signal. The second time difference may be a time difference between falling edges of the first component of the differential signal and the second component of the phase-shifted signal. Other circuits, systems, and methods are described.

Abstract: Duty-cycle correction circuits, clock distribution networks, and methods for correcting duty-cycle distortion are disclosed, including methods and apparatus for correcting duty-cycle distortion of differential output clock signals provided from a clock distribution network. In one such method, a single-ended clock signal is generated from differential input clock signals for distribution over a clock distribution network and from which the differential output clock signals are generated. A delay of a model delay path is matched to a propagation delay of the clock distribution network, and the single ended clock signal is adjusted to compensate for duty-cycle distortion.

Abstract: There is provided a system for comparing the phase characteristics of three generated clock signals, each having a unique phase relationship with an original clock signal, with the original clock signal and to select a signal based on the proximity of the phase characteristic of the three signals to the original signal. The selection of a clock signal that most closely approximates the original significantly reduces lock time when attempting to synchronize an internal clock with an external clock. Additionally, there is provided a method for comparing three clock signals with an original clock signal and selecting from the three clock signals one that is approximately in phase with the original clock signal.

Abstract: A delay-lock loop receives an input clock signal from the output of a programmable divider that receives a reference clock signal. The delay-lock loop includes a voltage-controlled delay line generating a plurality of delayed clock signals having different phases. A plurality of the delayed clock signals are combined to generate a plurality of output signals. During an initialization period, an initialization circuit sets the delay of the delay line to a minimum delay value and then compares this delay value to the period of the input clock signal. Based on this comparison, the initialization circuit programs the programmable divider and adjusts the number of delayed clock signals combined to generate the output signals. More specifically, as the frequency of the reference clock signal increases, the divider is programmed to divide by a greater number, and a larger number of delay clock signals are combined to generate the output signals.
