Working principle

The 402F19222IJR quartz crystal module is a miniaturized metal-in-pkg structure consisting of a quartz crystal, oscillator circuitry and metal packaging. An oscillator is typically composed of an amplifier, a positive feedback circuit, and a resonator. The quartz crystal acts as the resonator, and it causes the amplifier to oscillate at its resonant frequency. The oscillator circuitry is composed of an integrated circuit, a voltage regulator, and a counterelectrode voltage (C-V) module. These are connected to the crystal and can precisely control the frequency of the module. The frequency accuracy is determined by the quality of the quartz crystal and also by adjusting the parameters of the C-V module. The circuit is powered by a voltage regulator, usually either an AC or DC supply.

The 402F19222IJR quartz crystal module is an excellent choice for many high-precision applications due to its high accuracy, low power consumption and small size. Its frequency stability is high, and its frequency range is wide, making it suitable for many applications. It is easy to install and one of the most cost-effective options for high-frequency crystal applications.
