Working principle

The 8N3QV01KG-2002CDI8 consists primarily of a quartz crystal, a circuit that allows it to divide or multiply the frequency of the initial oscillator signal, and an amplifier which boosts the output of the oscillator before it goes to the output pins. The frequency of the oscillator is determined by the quartz crystal, which acts as a natural resonator, and can be adjusted by applying varying amounts of drive current to the crystal. The internal logic is used to control the drive current to the crystal, the oscillator output frequency, and the enable and output enable inputs, thus allowing for further application specific variations.

The 8N3QV01KG-2002CDI8 is programmed via an SPI interface, which allows for a variety of synthesis parameters to be programmed. It also offers synchronization, programmable power-down, and supply-tracking modes, as well as precise temperature compensation for optimal output performance. All of these features make the 8N3QV01KG-2002CDI8 an ideal solution for applications that require a precise, low power real-time clock.
