Oscillators: TC70N3A32K7680 Application Field and Working Principle

Oscillators are electronic systems that generate repetitive signals similar to sine waves. They are used in a wide range of industrial, automotive, and consumer electronics applications. The TC70N3A32K7680 oscillator is a surface mount crystal oscillator produced by Murata Manufacturing Company. It is designed for a wide range of applications and can generate a range of AC signals from 1-50 MHz.

TC70N3A32K7680 Description

The TC70N3A32K7680 is a small, surface mount electronic oscillator. It is designed to accept a crystal with a load capacitance of 12-30 pF and drive it with a transistor-based circuit. The frequency range is adjustable between 1-50MHz with an accuracy of 10ppm to 100ppm and a temperature range of -40°C to +85°C. The power consumption is 1.2mA maximum and the output is 3.3Vdc.

Application Field of the TC70N3A32K7680

The TC70N3A32K7680 oscillator is designed for applications that require precision AC signal generation and low power consumption. It is used in a variety of consumer applications, such as security systems; industrial applications, such as machining and manufacturing; automotive applications, such as navigation and communication systems; and medical applications, such as monitoring and therapeutic equipment.

Working Principle of the TC70N3A32K7680

The operating principle of the TC70N3A32K7680 oscillator is based on the resonant oscillation of a quartz crystal. The crystal is connected to a transistor-based circuit. When an AC signal is applied to the crystal, it vibrates at its resonant frequency. This causes the electric current to oscillate between the transistor and the crystal, generating an AC sine wave output.The TC70N3A32K7680 oscillator can operate in either the Pierce or Clapp mode. In Pierce mode, the circuit is configured such that the collector voltage of the transistor is lower than the supply voltage. This causes the transistor to conduct current, generating an AC signal. In Clapp mode, the voltage is inverted and the transistor conducts current in the opposite direction, preventing oscillation.

Conclusion

The TC70N3A32K7680 oscillator is a highly accurate and low-power surface mount crystal oscillator that can generate a range of AC signals from 1-50 MHz. It is used in a wide range of industrial, automotive, and consumer applications. Its operating principle is based on the resonant oscillation of a quartz crystal, driven by a transistor-based circuit. Its design allows it to operate in either the Pierce or Clapp mode, allowing it to produce a wide range of precise AC signals.
