402F30722IJR

Crystals are used in a variety of electronic components and products, from watches to electronic medical devices. The 402F30722IJR is a type of crystal specifically used for frequency control. This crystal oscillator makes use of a quartz crystal in combination with an amplifier, oscillator, and frequency divider circuit to provide precision frequency control.

The 402F30722IJR crystal oscillator utilizes a quartz crystal, usually made of AT-cut quartz, to provide precise timekeeping. Quartz crystals have piezoelectric properties which mean they have a characteristic whereby an electrical field is created when an external force is applied. By etching the quartz in a specific pattern, the crystal can then be used to provide an electrical signal that oscillates at an exact frequency.

This frequency is further refined and adjusted through the use of a frequency divider circuit and amplifier. The frequency divider circuit separates the signal from the crystal into several different frequencies, allowing for greater precision in the frequency control of the crystal. The amplifier then boosts the signal strength, allowing for a more reliable signal from the crystal. This combination of the quartz crystal and frequency divider circuit and amplifier gives the 402F30722IJR crystal oscillator its precision frequency control.
