Oscillators

An oscillator is an electronic circuit that produces repetitive electronic signals, most commonly sine wave, square wave, triangular wave and sawtooth waveforms. These waveforms are used frequently in communication systems. Oscillators come in many types, including phase-locked loops (PLLs), crystal oscillators, voltage-controlled oscillators (VCOs) and ring oscillators. The SIT1602BI-72-33S-32.768000D is an engineered oscillator that combines features of all these types of oscillators.

Working Principle

The SIT1602BI-72-33S-32.768000D is a crystal oscillator, meaning that it generates a precise frequency signal by vibrating a quartz crystal at a specific frequency. The oscillator includes a quartz crystal and an oscillator circuit. The oscillator circuit is composed of feedback and drive circuitry that interact with the quartz crystal to generate a stable oscillating signal at a specific frequency. The phase-locked loop (PLL) circuit is then used to adjust the frequency of the signal.

The adjustable PLL circuit uses feedback signals from the quartz crystal to adjust the output frequency. The adjustments are made using an externalvoltage control voltage (VCV) that can be used to adjust the frequency up or down by a factor of 4. In addition, the oscillator includes temperature compensation circuitry to minimize frequency drift due to temperature variations.

The SIT1602BI-72-33S-32.768000D oscillator can be used in a variety of applications where a highly accurate and stable frequency signal is required. Its wide frequency adjustment range makes it an attractive choice for industrial and automotive applications where a single frequency must be used over a wide temperature range.
