The Q 38, 40-JXS21-8-10/10-FU-WA-LF is a crystal oscillator circuit with multiple applications and a range of capabilities. It is typically used in the frequency control of motion detectors, radar receivers and transmitters, timing circuits, and communications circuitry.

A crystal oscillator utilizes the piezoelectric effect of quartz crystal to create an oscillating signal. A piezoelectric crystal is composed of positive and negative charged crystals that separate when exposed to a voltage, creating a piezoelectric effect. When current passes over the crystals, the crystals expand and contract along a certain axis and emit an alternating current.

The Q 38, 40-JXS21-8-10/10-FU-WA-LF crystal oscillator features a frequency range of 4-25 MHz, with three modes of operation - open-loop, closed-loop, and free-running. The frequency accuracy and stability of the oscillator depends on its mode of operation.

In open-loop operation, the crystal frequency is determined by the resistance between the terminals. By changing the resistance, the frequency of the crystal can be adjusted. The open-loop mode allows for maximum frequency control and highest accuracy in frequency control.

In closed-loop operation, the oscillator frequency is determined by the feedback from a period measuring circuit. This ensures exact frequency accuracy and stability, but at the expense of frequency control. Finally, in free-running mode, the frequency is determined by the frequency of the crystal alone.

The Q 38, 40-JXS21-8-10/10-FU-WA-LF crystal oscillator is used in a variety of applications such as timer circuits, frequency counter/frequency meter circuits, radar receivers and transmitters, motion detectors and communications equipment.
