Oscillators

Oscillators are devices that generate periodic, often similar, electrical signals. These signals are used in almost all electronic equipment, providing stable signals to synchronize and control digital logic and communications circuits. This article will focus on the application field and working principle of AST3TQ-V-16.384MHZ-50-C, a type of oscillator.

Application Field

AST3TQ-V-16.384MHZ-50-C oscillator is mainly used in data storage system, data communication system and other electronic equipment. As an oscillator, its frequency spectrums includes 16.384MHz, which is the ideal choice for a clock signal source because of its wide range of frequencies.

The oscillator is general composition of quartz crystal with clock frequency, frequency adjustment with oscillation circuit, frequency stabilization with a temperature compensation circuit, and amplifier with a buffer circuit. The characteristics of the oscillator are very stable: a frequency stability of 5.0ppm over the temperature range of -40 °C to +85 °C. It also has a high shock resistance with a shock-resistant rate of over 95 percent.

Working Principle

AST3TQ-V-16.384MHZ-50-C oscillator is based upon a quartz element as the frequency basic. When an AC voltage is applied to the quartz crystal, its frequency will be changed. By adjusting the AC voltage, the quartz crystal frequency can be adjusted more or less, and this affects the crystal oscillator output waveform. The oscillator also has a temperature compensation circuit to ensure a constant and accurate oscillation frequency over a wide temperature range.

When the voltage is applied to the quartz crystal, its vibration pattern changes which sets up an internal frequency. This frequency is then amplified by the amplifier and buffer circuits, and used as the output for the oscillator. This output is then divided down to more accurate frequencies by the phase frequency divider. The phase frequency divider is responsible for providing the necessary signals for the system, which are proportional to the oscillator’s output frequency. The output from the divider is then sent back to the oscillator, to adjust the frequency of the oscillator.
