Crystals have long been used for a variety of purposes, from timekeeping to navigation. In the modern world, crystals are utilized in microelectronic applications such as frequency control, resonators, oscillators, receivers, and filters. Among these crystals, the 402F30022IDT is a type of precision crystal oscillator with an ultra low power consumption. It is well suited for low power RF applications such as cellular phones and satellite receivers.

The 402F30022IDT crystal oscillator has an operating temperature range of −20 to +85 °C. It is accurate to ±20 ppm at 25 °C, and +175ppm at any temperature range. Furthermore, it provides a low-power solution, drawling only 6.5mA at a 3V supply voltage. It is also designed with a high maximum drive level of 10mA.

The 402F30022IDT comes in a small 4 mm x 3.2 mm quad-flat package (QFP) with no lead (Pb) construction. It is rated “RoHS compliant”, indicating that it is free from hazardous substances in production. This makes the crystal suitable for use in delicate and environmentally friendly applications such as medical personel.

The working principle of the 402F30022IDT is based on the mechanical properties of its crystal. Inside the crystal, a piezoelectric material is charged, then discharged, in frequent cycles. This action produces a pulse that has an oscillating frequency. The clock speed is determined by the size of the crystal. In the case of the 402F30022IDT, the size of the crystal is specified as 40 kHz.

The clock pulse is then tuned with resistors, capacitors, and inductors. These components form a tank circuit, which is used for amplitude control and frequency adjustment. The output signal is then generated by the oscillation of the tank circuit.

The 402F30022IDT is a high performance device with a long service life, low power draw, and compact design. Its wide temperature range and crystal-based frequency control makes it suitable for testing, measuring and consumer applications. With its excellent features and price, the 402F30022IDT is an ideal choice for a variety of applications.
