Oscillators

An oscillator is an electrical device or system that produces periodic, oscillating electrical signals on its output. It can be used to convert electrical energy into mechanical energy, or to automatically control electrical circuits. Examples include clock oscillators, precision voltage sources, and ignition systems. Oscillators are also used in analog and digital communications systems.

AX7HCF1-270.0000C Application Field and Working Principle

AX7HCF1-270.0000C is a high-reliability oscillator series manufactured by Dali Technology. It is a frequency-stabilized temperature-compensated crystal oscillator (TCXO). The operating temperature range is from -20°C to +70°C and can be used for high-precision frequency synthesis, precise frequency extraction, and frequency stability in the range of ±1*10-6. Its output frequency range is from 0.5MHz to 70MHz.

AX7HCF1-270.0000C\'s application field is mainly used in satellite receivers, microwave cellular networks, medical equipment, etc. It has small size, high reliability, low power consumption, and high temperature stability. It also has ultra-high accuracy, high stability and strong output amplitude etc. Its comprehensive performance is far superior to similar products.

The working principle of AX7HCF1-270.0000C is based on the quartz crystal oscillator. Quartz crystals are piezoelectric materials, so when a voltage is applied to them, they vibrate at a specific frequency. This vibration in quartz crystals is an alternating voltage, usually referred to as the oscillator output voltage.

The frequency is determined by the physical size of the quartz crystal used and can vary somewhat depending on the temperature and other conditions. The AX7HCF1-270.0000C is temperature-compensated and its quartz crystal is carefully selected to ensure stability across a range of temperatures, from -20°C to +70°C. The output frequency is also internally compensated for aging.

In addition, a high-precision voltage-controlled oscillator (VCO) and a programmable divider are used to achieve the required frequency, and an analog output can also be provided to provide analog frequency output for AD / DA conversion.

In conclusion, AX7HCF1-270.0000C is a high-reliability oscillator series, its application field is mainly used in satellite receivers, medical equipment, microwave cellular networks, etc. It has small size, high reliability, low power consumption, and high temperature stability. It also has ultra-high accuracy and high stability, and the working principle is based on the quartz crystal oscillator.
