Crystals are the most commonly used timing devices in electronic circuitry due to their convenient size, stability, and accuracy. The AH-32.768KEWF-T is a temperature-compensated crystal oscillator (TCXO) used in many applications due to its high frequency stability and low power consumption.

The AH-32.768KEWF-T is capable of providing clock frequency of 32.768 kHz with a voltage ranging from 2.25 V to 3.5 V. It is a small, surface-mount package with dimensions of 2.5 mm x 1.2 mm x 0.6 mm. The TCXO utilizes parameters from a proprietary temperature-compensated oscillator (TCXO) allowing for low-power consumption, high frequency accuracy, and wide operating temperature range.

The AH-32.768KEWF-T is used in many applications including but not limited to clock-recovery in digital communications systems, time-keeping and time-stamping systems, automatic meter-reading systems, and remote sensing systems. It provides a convenient solution for applications requiring a small, stable, and accurate reference clock signal.

The TCXO works by using a quartz crystal oscillator to create an oscillating signal at a very precise frequency. A temperature-compensated oscillator (TCXO) is a type of oscillator that is designed to maintain a constant frequency over a wide range of temperatures. The AH-32.768KEWF-T utilizes a special ASIC that is able to stabilize the oscillation frequency over temperature. The ASIC takes into account changes in the crystal’s capacitance and resistance due to temperature and adjusts the bias voltage accordingly. This ensures that the output frequency of the oscillator remains constant over a wide temperature range.

In addition to the temperature compensation, the AH-32.768KEWF-T also employs a frequency trimming method to further improve its frequency accuracy. The frequency trimming is done by adjusting the bias voltage and adjusting the capacitance of the crystal in order to make small adjustments to the frequency. This allows the oscillator to achieve an ultra-high frequency accuracy of ±2.5ppm.

The AH-32.768KEWF-T is an ideal choice for applications that require a small, stable, and accurate reference clock signal. With its high frequency accuracy and wide operating temperature range, it is well-suited for many applications. Additionally, its low power consumption makes it an ideal choice for battery powered devices.
