Crystals are a fundamental element for many electronic products, acting as an oscillator for frequency control, time base generation and radio frequency (RF) oscillation. The frequency and accuracy of a crystal oscillator depend on the specific crystal material and the circuit form it is put into. One of the most commonly used crystals used in many electronic products is the ABS07-32.768KHZ-4-T crystal.

The ABS07-32.768KHZ-4-T (hereafter referred to as 32.768 crystal) is a Tuning Fork Quartz Crystal manufactured by Murata Electronics. The standard frequency for the 32.768 crystal is 32.768kHz and the current specification range is from 30kHz to 35.5kHz. It is most often used for real-time clocks, micro controllers, wireless devices, and microprocessors. These devices often require accuracy in the microsecond range and the 32.768 crystal is known for its excellent temperature and frequency stability.

The ABS07-32.768KHZ-4-T crystal is packaged in a 4-terminal SMT package. These terminals include a ground (GND) pin, two drive pins (DR1 and DR2) and a adjustment pin (ADJ). The frequency is adjusted using a external capacitor connected between the adjustment pin (ADJ) and ground (GND). The two drive pins (DR1, DR2) provide a DC bias to the crystal which is necessary for proper operation. Typically the DR1 and DR2 pins are driven with a low AC voltage.

The 32.768 crystal operates based on the principles of Quartz Resonance. Quartz crystals are cut in a rectangular shape and when a voltage is applied to it, the crystal vibrates at its resonant frequency. This oscillation frequency is determined by the crystalline properties of the quartz material and by the crystal’s size and shape. The temperature and other environmental factors also affect the operating frequency, as the properties of the quartz material change with temperature and other conditions.

The 32.768 crystal’s frequency stability is determined by the quality and manufacturing process of the crystal. The quality of the crystal heavily affects the aging, drift, and shock tolerance of the crystal. The quality is usually expressed in ppm/°C, which is the change in frequency relative to one part-per-million (ppm) per degree Celsius of temperature variation. The commonly used Murata ABS07-32.768KHZ-4-T has a stability of ±20ppm, which is within a temperature range of -20°C to +70°C.

The 32.768 crystal is used in a variety of applications, most notably in medical and automotive systems. In medical systems, the 32.768 crystal is used for the timing of imaging equipment such as magnetic resonance imaging (MRI) and computed tomography (CT) scanners. In automotive systems, the 32.768 crystal provides accurate timing for engine control systems, airbag controllers, and other safety-critical features. It is also widely used in various portable electronic products such as PDAs, handheld game consoles, cell phones, and other wireless devices.

The 32.768 crystal is an integral part of many electronic devices. Without it, many devices would not be able to operate reliably and accurately. It is one of the largest contributors to the accuracy and stability of many systems, and is a key component in enabling advancements in medical and automotive systems.
