416F25025ALR application field and working principle

A crystal resonator, such as the 416F25025ALR, is a device used to control the electrical frequency of a circuit. It utilizes the natural oscillations of a quartz crystal to accurately produce a specific frequency. Quartz crystals are piezoelectric material, meaning that when an electrical field is applied, the material will physically vibrate at a very precise frequency

The 416F25025ALR is a low-frequency oscillator, typically Vibration or Temperature compensated. These types of oscillators enable excellent temperature stability and low stop-start power consumption. This makes the 416F25025ALR useful in a variety of applications such as clocks, watches, synchronization, and sensing.

The 416F25025ALR is constructed using an AT-cut quartz crystal and a holder. The quartz crystal is wired in one-quarter wave resonance mode with two metal electrodes on the top and bottom of the crystal, and one electrode on each lateral side. This arrangement creates a quadrature oscillator, meaning that the oscillation is inversely proportional to its capacitance. This arrangement also reduces the device\'s sensitivity to acoustic noise and environmental changes.

The 416F25025ALR is designed for use in high-temperature applications up to 250 degrees Celsius. Its temperature compensated oscillator is designed to minimize frequency drift at different temperatures, providing excellent long term stability. Its maximum drive level is 5 µW, and generates a 0.5 V p-p sinewave output.

The 416F25025ALR is a low cost, high stability oscillator widely used in a range of applications. Its excellent frequency stability, small size, and wide temperature range make it suitable for many applications. It is frequently used in the automotive, medical, industrial, and communications sectors.
