Working Principle

The ABM8W-18.7500MHZ-7-B1U-T3 crystal consists of a quartz crystal resonator which is sealed in a can and mounted on a printed circuit board or other substrate. The crystal resonator is made of a quartz crystal which has been cut into a rectangular shape and then electrodes have been applied to the cut edge of the crystalline lattice. When a voltage is applied to the electrodes, the quartz crystal will vibrate or "resonate" at a precise frequency, determined by the thickness, cut and shape of the crystal. This frequency will remain very stable, even in the presence of temperature variations, vibration and aging.

The ABM8W-18.7500MHZ-7-B1U-T3 crystal has a frequency response of 18.7500MHz, a temperature stability of +/- 20ppm over the temperature range of -40°C to +85°C and a standard load capacitance of 7 pF. The crystal can be operated in the temperature range of -10°C to +60°C and is rated for an operating voltage of up to 4.7V. It has an ESR of 45Ohms and can support up to a 200mA current rating.

The packaged crystal can be used in a variety of configurations, depending on the application. The most common applications are parallel resonance, series resonance, and series-parallel resonance. Parallel resonance is used in oscillator circuits which are used to generate and transmit a stable frequency signal. Series resonance is used in oscillator circuits to generate a pulse train. Series-parallel resonance is used in timing circuits to generate the clocks and timing signals used to control the digital circuits.

The ABM8W-18.7500MHZ-7-B1U-T3 crystal is a high-precision device which is capable of providing precise frequency and timing references for a wide range of applications. It provides a stable and reliable source of frequency and timing signals, and is capable of delivering accurate, repeatable results over a wide temperature range.
