Oscillators are essential electronics components which are used to generate a recurring periodic signal (or waveform) with a precise amplitude, frequency and phase. These signals can be used to create, transmit or receive clocks or other types of signal. One such device is the ECX-P32CM-32.768 oscillator, which is generally used for real-time clock (RTC) applications. This article will discuss the application fields and working principle of ECX-P32CM-32.768 oscillator.

Applications

The ECX-P32CM-32.768 oscillator is mainly used for RTC applications, where it is required to provide an accurate reference clock signal to meet system timing needs. This oscillator can also be used in microcontrollers, where it is needed to generate an accurate reference clock signal to drive peripherals such as UARTs, timers and SPI interfaces. In addition, this oscillator is also used in various communication systems, such as Bluetooth, Wi-Fi and mobile phones. Also, this device can be used in embedded systems like medical applications, automotive applications and smart meters.

Working Principle

The ECX-P32CM-32.768 oscillator consists of a silver plated quartz crystal, a pair of high stability, temperature independent biasing capacitors, and a CMOS output buffer. The quartz crystal is generally cut in a specific shape so that it is able to vibrate when an applied voltage is given to it. The rich number of crystals and associated capacitors, allow the crystal to oscillate at its resonant frequency.The external capacitors circuit connected to it helps to cause the frequency of oscillation to have a high-quality factor (Q factor) and a low-temperature coefficient (TC). The external capacitors circuit also optimizes the energy transfer between the crystal and the output buffer.When a supply voltage is applied to the oscillator, the quartz crystal starts vibrating, and produces a high quality, low-distortion output wave form at it’s specified frequency. The output driver then takes the signal from the crystal and converts it into a standard CMOS logic level signal before it is sent out.

Conclusion

The ECX-P32CM-32.768 oscillator is an ideal choice for applications requiring a high-precision reference clock. It offers a buffer capable of driving wide supply range as well as high quality, low-distortion output wave forms. The high stability, temperature independent biasing capacitors, and CMOS output buffer make it a reliable choice for many applications.
