Introduction

Oscillators enable the generation of a precise frequency from an increase or decrease in voltage or temperature. The ECS-3951M-100-AU-TR is an example of such an oscillator, offering excellent performance and reliability in time-critical applications. The goal of this article is to discuss the application field and working principle of the ECS-3951M-100-AU-TR oscillator.

Application Field

The ECS-3951M-100-AU-TR oscillator is designed for use in communications systems, radio broadcast, and instrumentation applications. It offers high precision frequency output, with an accuracy of ±50ppm over a wide temperature range (-40°C to 85°C). It is also extremely reliable, with an MTBF of up to 5 million hours.The ECS-3951M-100-AU-TR is a small, low-power oscillator, with a footprint of just 8.5 x 8.5mm. This makes it suitable for space-constrained applications, such as embedded systems and portable devices. The device can be powered from a single +5V supply, making it ideal for battery-powered systems.

Working Principle

The ECS-3951M-100-AU-TR oscillator comprises a series of mechanical components, such as springs, cams, an armature, and a pendulum. The movement of these components creates an oscillation of the armature, which is converted into an electrical signal.The frequency of the oscillation is then measured and adjusted by the device’s electronic controls. An initial frequency is set by the clock, which is then maintained by a feedback circuit that senses changes in frequency. This ensures that the frequency output of the oscillator remains constant and accurate.

Conclusion

The ECS-3951M-100-AU-TR oscillator is a reliable and accurate solution for time-critical applications, such as communications systems, radio broadcast, and instrumentation. It is small and low-power, making it suitable for space-constrained applications, and powered from a single +5V supply. The device works by converting mechanical oscillations into an electrical signal, which is then adjusted by a feedback circuit to maintain accuracy of frequency output.
