Oscillators are electrical circuits which, when acted upon by an energy source, produce an output signal with a frequency that is a distinct multiple of the input source frequency. ECX-P37CM-14.7456 is an example of this type of component, specifically designed to produce very stable output signals. In this article, we will explain the application field and working principle of the ECX-P37CM-14.7456.

Application Field

The ECX-P37CM-14.7456 is a precision oscillator with a center frequency of 14.7456MHz, designed to provide a stable reference clock signal for applications such as personal computers, satellite navigation systems, communications systems and industrial control systems. It is capable of providing up to plus or minus 5ppb drift in frequency due to temperature or aging variations. The ECX-P37CM-14.7456 can also operate over a wide range of supply voltages, from 2.0V to 3.3V, making it suitable for use in a variety of applications. In addition, the device is available in a small digital package (TO-252-6L) for improved performance and mounting density.

Working Principle

The ECX-P37CM-14.7456 is based on a standard quartz crystal oscillator circuit. Quartz crystals are piezoelectric materials that vibrate when a voltage is applied across their electrodes. The frequency at which a crystal oscillator will vibrate is determined by its capacitance, inductance and size. The frequency stability of the ECX-P37CM-14.7456 is achieved by using a high-purity quartz crystal, carefully controlling the capacitance across the crystal, and temperature compensation techniques. The circuit also includes a voltage-controlled oscillator (VCO) which is used to adjust the output frequency of the device over a range of +2ppm/-1ppm. The output frequency is trimmed to within 5ppb by adjusting a trimming capacitor.

The ECX-P37CM-14.7456 provides a very stable reference clock signal, which can be used to eliminate timing inaccuracies in a wide range of applications. Its small size and low power consumption make it an ideal choice for applications where space and power are at a premium.
