Oscillators such as the ECX-L37BN-33.000 are typically used in communications systems, instrumentation, and consumer electronics, particularly for timing and synchronization purposes. In particular, its small form factor and low power requirements make it a popular choice for handheld and portable electronic devices. In addition, this device is designed to provide very low phase-noise and jitter performance which makes it highly suitable for applications that require precision and accuracy.

Working Principle

The ECX-L37BN-33.000 crystal oscillator operates using a quartz crystal resonator which vibrates at a specific resonant frequency. A quartz crystal resonator is made up of a thin quartz slice typically 20 to 40 µm thick. This thin slice of quartz is mounted in a housing and two metal electrodes are attached to the quartz slice on either side forming a “tank circuit”. When a voltage is applied across the electrodes, the quartz vibrates, producing a steady sine wave output at the resonant frequency.

The crystal is surrounded by a circuit which provides electrical feedback to ensure that the output frequency remains constant, even when environmental factors such as temperature or pressure change. This circuit typically consists of an amplifier and a capacitor connected to the quartz to form a negative feedback loop, which makes the oscillator stable and has low phase-noise characteristics. Moreover, this circuit is designed to ensure that the current applied to the quartz is kept constant, so that the output frequency remains constant over time.

Conclusion

The ECX-L37BN-33.000 crystal oscillator is an excellent choice for timing and synchronization applications in communications, instrumentation, and consumer electronics due to its high stability and low phase-noise performance. This device utilizes a quartz crystal resonator to produce a steady sine wave output at its resonant frequency, and is surrounded by an electrical feedback circuit that ensures the output frequency is maintained even when environmental factors change. With its small form factor and low power requirements, this oscillator is ideal for handheld and portable electronic devices that require reliable and accurate timing and synchronization.
