Crystals have been used for decades as a source of precise timing in electronic circuits. ABS09-32.768KHZ-1-T is one type of crystals employed for precise timing applications. It is a surface-mount device (SMD) tuned to 32.768 kHz.

ABS09-32.768KHZ-1-T operates in the frequency range of 32.76 to 32.80 KHz. Its vibrational frequency is known to be precise and stable with a temperature coefficient of ±40 ppm. This is considered to be one of the highest tolerance compensation ranges available in the market today allowing precise timing over a broad temperature range.

The typical frequency stability of the ABS09-32.768KHZ-1-T is ±20 ppm over a temperature range of -20°C to 70°C. This makes it suitable for precise timing applications that requires high accuracy over wide temperature variations.

ABS09-32.768KHZ-1-T draws very low current because it utilizes an oscillator circuit. This makes it suitable for low power applications such as in watches. It also has a high shock and vibration resistance and is immune to electromagnetic interference.

ABS09-32.768KHZ-1-T is mainly employed in high precision timing applications such as in timing circuits for microprocessor/microcontroller applications, systems employing phase-locked-loop (PLL), quartz watches, automotive, GPS or any application that requires precise timing and frequency.

The working principle of a ABS09-32.768KHZ-1-T is based on the piezoelectric effect. The piezoelectric effect is a phenomenon in which an application of an electrical field to a crystal causes a mechanical deformation in the crystal lattice. This is known as deformation potential and is a measure of the elasticity of the crystal lattice. When voltage is applied to the crystal, the lattice becomes distorted and a corresponding kinetic energy is created.

The kinetic energy generated due to the application of the electrical field causes the crystal to vibrate at a certain frequency. The frequency of vibration is determined by the mechanical properties of the crystal and does not change with time or temperature. This is why crystals are used for precise timekeeping tasks.

ABS09-32.768KHZ-1-T contains two metal plates at each end and a gap in between them. The application of a voltage causes the lattice to vibrate at a frequency that is determined by the gap between the plates. This vibration is detected by an oscillator circuit and converted into a precise timing signal.

ABS09-32.768KHZ-1-T makes use of the piezoelectric effect to generate a precise and stable frequency over a wide temperature range. It is an ideal choice for applications that require accurate and reliable timing.
