Oscillators

Oscillators are electronic devices or circuits that produce repetitive, periodic oscillations. Oscillators are mostly used to achieve synchronization or timing in various electronic systems. They are used to maintain a sequence of action for a particular purpose, whether it is performing a critical task or just as a reference to be matched up with other waveforms.

SIT1602BI-22-30E-12.000000D application field and working principle

SIT1602BI-22-30E-12.000000D oscillators are ideal for use in radar, wireless and consumer electronic applications. These oscillators can provide stable frequency signal generation with outstanding phase noise performance. The SIT1602BI-22-30E-12.000000D is a high performance 1.2 GHz low jitter oscillator. It has a variety of output types, including single-ended (CMOS/TTL) and differential (LVDS/PECL/LVPECL) outputs.

The working principle of the oscillator is based on the concept of positive feedback. A basic oscillator circuit consists of an amplifier or buffer, a frequency-determining element, and a feedback loop that provides positive feedback from the output of the amplifier back to the input. The frequency-determining element could be an inductor, capacitor, or both. When the gain of the amplifier is equal to one, the positive feedback establishes a sinusoidal signal at the output of the circuit.

The frequency of the oscillation, or the frequency of the output signal, is determined by the characteristics of the frequency-determining components, which are either an inductor (L) or a capacitor (C). The frequency of the oscillation can be calculated using the following formula:

Frequency = 1/2π√LC

Where F is the frequency, L is the inductance of the inductor (or inductors), and C is the capacitance of the capacitor (or capacitors).

The SIT1602BI-22-30E-12.000000D oscillator features a tight phase noise of -148 dBc/Hz at 10 kHz offset, 0.7 ps RMS jitter, and a ±20 ppm frequency stability over temperature. It operates from a +3.3V or +5V supply, and has a fast start-up time of 1 ms. The oscillator is also optimized for low power consumption of 0.4 W, and has patented noise suppression technology for lower EMI/EMC radiation.
