Oscillators

Oscillators are electrical or electronic circuits that generate periodic electrical signals, such as a sine wave or a square wave. They are essential components used in many electronic communication, measurement, and control systems.

SIT1602BI-81-XXE-7.372800X: Application Field and Working Principle

The SIT1602BI-81-XXE-7.372800X oscillator is a laser trimmed oscillator operating over the frequency range of 450kHz to 5MHz. It is typically used in low phase noise frequency synthesis applications, such as Wideband Code Division Multiple Access (WCDMA) and Time Division Multiple Access (TDMA) wireless communications systems,, as well as TV and cable systems. The SIT1602BI-81-XXE-7.372800X oscillator is based on a tuned circuit, which consists of an inductor-capacitor (LC) tank circuit that provides an inductive reactance, an electrical resistance, and a capacitive reactance. The oscillator output is then generated from this oscillating LC circuit. The tank circuit is tuned to a specific frequency that determines the oscillation frequency of the oscillator. It can be varied by changing the capacitance and/or inductance of the tank circuit. The SIT1602BI-81-XXE-7.372800X oscillator is also designed to provide excellent phase noise performance as well as stability over a wide temperature range. It is able to achieve this level of performance because of its laser trimmed frequency control circuitry. This circuitry is used to accurately calibrate the frequency of the oscillator and to compensate for changes in temperature. The SIT1602BI-81-XXE-7.372800X oscillator is packaged in a hermetically sealed enclosure, which provides a long product lifetime and reduces vibration and noise interference. It is ideal for use in applications that require a low phase noise oscillator that is capable of operating over a wide frequency range.
