The oscillator has two major components, the phase-lock loop (PLL) and the crystal. The PLL controls the frequency of the crystal by manipulating the phase of the signal. The SIT9002AC-23H33SK has a frequency range of 4.096 MHz to 822.2 MHz with a voltage stability of 8.1 VDD.

Application Field

The SIT9002AC-23H33SK is used in a variety of applications, including radio frequency (RF) communications and instrumentation. It is particularly well suited for short-range communications such as Wi-Fi, Bluetooth, and ZigBee. It is also used in radar applications, frequency synthesizers, and precision timing applications such as GPS.

Working Principle

The working principle of the SIT9002AC-23H33SK is relatively simple. The oscillator uses the principle of resonance to produce a repeating wave-like signal at a specific frequency. The signal is produced by the oscillator driving an electric current through the capacitor of the crystal. The current is then converted into an alternating voltage waveform. The waveform is then filtered and amplified by the PLL to produce a signal at the desired frequency.

The frequency of the signal is controlled by the PLL, which can be set to any specific frequency within the range of the oscillator using external control signals. The oscillator is capable of generating a stable signal with a frequency accuracy of ±1.5 ppm over a temperature range of -40°C to 80°C.
