摘要： A cyclical pulsing oscillator having a pulse repetition rate close to a crystal resonant frequency in an oscillator provides more useful start-up energy to the crystal oscillator circuit and thus provides much faster start-up time. The start-up pulsing oscillator runs for a number of cycles or until the crystal oscillator amplitude as built up to a desired value. The pulsing oscillator may have a repetition rate of from about one-third to about one-half the crystal resonant frequency, thus providing more useful start-up energy to the crystal oscillator circuit.

摘要： A crystal oscillator is started in a high power mode for a certain period of time to ensure starting oscillation with average grade crystals, then once the certain time period is over the oscillator switches into a low power mode and sustains oscillation with energy pulses triggered by and synchronized with the oscillator output frequency. These energy pulses may be generated on the positive, negative or both positive and negative edges of the clock output waveform.
