Oscillators are components that produce periodic electrical signals with a fixed frequency and amplitude. Applications range from low-frequency analog signal generation to high-frequency digital synchronization and timing. The Swiss manufacturer ASKH produces a range of high-performance oscillators for different application areas and meeting varying customer requirements. This article will focus on the ASKH5-32.768KHZ-LT oscillator.

The ASKH5-32.768KHZ-LT oscillator is an affordable, environmentally-friendly, low-power quartz crystal oscillator. Operating in a wide temperature range of -40° C to +85° C, This oscillator also offers excellent performance and accuracy, with maximum frequency deviations of ±15 ppm, and minimum phase noise of -135 dBc/Hz. The oscillator also supports a wide range of power supply voltages, from 2.8 V to 5.5 V.

The oscillator has a wide range of applications, from timing and synchronization in cellular networks and radio transmission systems to real-time clock (RTC) applications. It is also ideal for embedded communications, such as Bluetooth, Zigbee, and 802.15.4, as well as motor control applications and memory synchronization.

In terms of its working principle, the oscillator is composed of a quartz crystal and an electronic circuit. The quartz crystal is a piezoelectric element, i.e., it emits electrical signals when mechanical disturbance is applied to it. The quartz crystal is connected to an electronic circuit which is designed to keep the quartz crystal in resonance. Therefore, when an alternating electric current is applied to the quartz crystal, it will cause the crystal to vibrate at its resonant frequency. The electronic circuit is then able to detect the frequency and convert it into a stable, periodic electric signal.

To further optimize the signal stability and frequency accuracy, thermostatic techniques can be used, which consists of temperature-controlled elements, such as Pt1000 resistors. By adjusting the resistance of these elements, the frequency accuracy over a wide temperature range can be improved significantly.
