Oscillators

A oscillator is a device or system that produces a regular, repeating pattern or signal that oscillates between two states. It is a type of electronic component that produces a continuous, repetitive, stable signal over a wide range of frequencies, usually used to generate a clock signal for timing or synchronization purposes. The SIT9120AI-1BF-XXE74.175824G device is a low-cost, ultra-low-power, wide-band, CMOS synthesizer with 24-bit accuracy and direct conversion, supporting both time-division-multiplexing (TDM) and frequency-shift-keying (FSK) protocols.

The SIT9120AI-1BF-XXE74.175824G oscillator has a wide range of applications from clock and data signal synthesis for timing and synchronization purpose, to radio frequency communication systems. The device is designed for consumer, industrial and automotive applications such as automotive infotainment systems, Wi-Fi, Zigbee, Bluetooth, GPS receivers, IoT gateway solutions, access points, and cellular base station applications.

Working Principle

The operating principle of the SIT9120AI-1BF-XXE74.175824G oscillator is based on the direct conversion principle. It uses a phase-locked loop (PLL) to generate a clock signal at a selected frequency, and the LC tank circuit to accurately tune the frequency. The crystal oscillator is the main component of this device. The package contains a specially designed crystal resonator that ensures high frequency accuracy over a wide range of temperatures.The SIT9120AI-1BF-XXE74.175824G oscillator uses an on-chip voltage-controlled oscillator (VCO) circuit with an output frequency range from 10kHz to 4 GHz. The output frequency is adjustable in 1 ppm steps using an analog voltage or 10-bit digital code. The device also features a low current consumption of 0.9 mA, for a very low power operation.
