Oscillators

Oscillators are electrical circuits that generate an oscillating signal, typically used in communication systems, electronic circuits and other applications that involve electrical waveforms. The ECX-L37CM-32.768 crystal oscillator is one of the most widely-used oscillators and has many applications.

ECX-L37CM-32.768 Application Field

The ECX-L37CM-32.768 series oscillator is available in an industry standard, low profile 5.0 x 3.2 mm package, making it ideal for use in space-constrained designs. It is optimized for low power, and can operate over a wide frequency range. It is commonly used in microcontroller system, broadcast receivers, data-receiving systems, portable transceivers, medical systems and commercial devices, such as smart home appliances, lifestyle products and consumer electronics.

Working Principle

The ECX-L37CM-32.768 oscillator contains a quartz crystal that is cut and poled to form a resonator. The resonator acts as a frequency selective filter for the applied electrical signal and allows only those signals that match its resonant frequency to pass. During oscillation, the crystal vibrates in response to an alternating current signal delivered by the oscillator. The crystal has a physical resonance of 32.768kHz and absorbs a certain amount of power, causing it to vibrate at its resonance frequency, thereby providing the output signal.

The crystals used in the ECX-L37CM-32.768 series oscillators are made of quartz which offers excellent frequency stability and allows the oscillator to maintain a close relationship with the resonance of the crystal. The frequency stability is usually ±20-100 ppm, depending on the crystal used. To achieve higher accuracy over longer time periods, temperature compensation can be used to reduce the effects of temperature drift on the crystal’s frequency.

The ECX-L37CM-32.768 series oscillators are designed for low power consumption. The typical power consumption is only around 25uA. This makes them suitable for applications that require low power operation, such as battery powered devices. They are also designed to be reliable since they are immune to any phase noise, power supply noise or EMI.

Conclusion

The ECX-L37CM-32.768 crystal oscillator is a reliable and low power oscillator that is suitable for a wide range of applications such as microcontroller systems, broadcast receivers, data-receiving systems, portable transceivers, medical systems and consumer electronics. Its frequency stability and wide operating range make it a popular choice for many designers. It is also available in industry standard packages, allowing it to be integrated into different circuit designs with ease.
