ECX-P37BN-1244.000

Oscillators

An oscillator is an electronic circuit which produces a periodic oscillating signal, often a sine wave or a square wave. It is a component used for maintaining a consistent timing interval and frequency in a range of applications from low-frequency audio signals to microwaves, and from triggering events to frequency modulation and phase-locked loop servo mechanisms. One of the most common applications of oscillators is the small, economized ECX-P37BN-1244.000.

Application Field

The ECX-P37BN-1244.000 is an ultra-low power oscillator which combines stability with economy. It is suitable for a range of low-power and battery-powered applications including watches, alarms, keyless entry systems, and other precision applications.

Designed for a wide frequency range, the ECX-P37BN-1244.000 has a nominal frequency range of 0.18 to 36MHz, making it suitable for many timing and synchronization applications. It also offers another advantage in the form of its active Crystal ESR (Equivalent Series Resistance) of 2.6 ohm, which reduces current consumption further than most traditional oscillators. By optimizing current consumption, this active Crystal ESR feature can enable a long battery life of up to 12 months.

Due to its tiny 3.2 x 2.5mm footprint and integration of an automatic start-up delay where the oscillator needs to warm up in order to achieve optimal frequency and accuracy, the ECX-P37BN-1244.000 is a great choice for small, cost-sensitive applications.

Working Principle

The ECX-P37BN-1244.000 draws its power from a battery or 3.3V power supply, using tiny currents to create accurate timing signals. Its components oscillate in a four-stage oscillation circuit based on a quartz crystal, producing output signals with extremely low energization (power consumption).

The oscillator combines the quartz crystal-based oscillator with an automatic start-up delay. This ensures that the oscillator is able to warm up and achieve the desired frequency and accuracy before the signal output begins.

The ECX-P37BN-1244.000 is ideal for timing and synchronization applications, especially in battery-powered and low-power applications. Its high stability and low energy consumption, along with its compact size and automatic start-up delay, make it a great choice for increasingly small and precise applications.
