Oscillators: Application Field and Working Principle of AX7PBF4-800.0000T

Oscillators are electronic devices that generate periodic, oscillating electrical signals with waveform characteristics (amplitude, frequency, and phase) determined by their intended application. These devices are used in a wide range of applications, including but not limited to communication systems, radar, navigation, and medical systems. Oscillators are also used as frequency sources for measurements, calibration, and performance testers. This article will focus on one particular type of oscillator, the AX7PBF4‑800.0000T, and discuss its application field and working principle.

Application Field of AX7PBF4-800.0000T

The AX7PBF4‑800.0000T is a temperature compensated crystal oscillator (TCXO). TCXOs are used to provide an extremely stable frequency output for applications that require it, such as those with stringent frequency control requirements. The AX7PBF4‑800.0000T is specifically designed for Satellite Mobile Terminal (Satellite Phone) applications.

Additionally, the AX7PBF4‑800.0000T has the ability to support multiple communication channels, thus making it suitable for tracking, recording, and monitoring devices.

Working Principle of AX7PBF4-800.0000T

The AX7PBF4‑800.0000T is a voltage‑controlled oscillator (VCO) that features a low phase noise voltage controlled crystal oscillator (VCXO) core. It works by utilizing a quartz crystal as a frequency reference to generate a stable and precise frequency output. The quartz crystal is tuned to the desired frequency by applying an externally controlled voltage. The crystal establishes the series resonant frequency (SRF) for the oscillation. An internal amplifier amplifies and shape the oscillation and then the phase detector compares the output signal with the reference clock signal. The phase detector adjusts the control voltage to the VCXO core accordingly to maintain frequency accuracy and phase stability over temperature variations. The AX7PBF4‑800.0000T is highly reliable and provides excellent frequency stability over a wide temperature range, making it perfect for applications that are sensitive to environmental conditions.
