Introduction to Oscillators

Oscillators are electrical circuits that produce a periodic waveform, such as a sine or square wave. They are used in many applications such as radios, cellular phones, and even in some digital circuits. They are also often used in measuring systems such as optical encoders and anemometers. Oscillators are commonly used for generating a stable output frequency and also for regenerating cryptographic keys.

The purpose of an oscillator is to generate a periodic waveform, such as a sine, square or triangle wave, which can be used for a variety of applications. These waveforms can be used to control motors, create waveform patterns for sound synthesis, or even generate power for electrical circuits. Oscillators are also used to control the frequency of a signal, for example in the case of a radio transmitter or receiver. Oscillators can also be used as a clock source in digital systems.

SG-615P 3.6864MC0:PURE SN Application Field and Working Principle

SG-615P 3.6864MC0:PURE SN (PURE SN) is a high precision, high stability mixed signal frequency sine wave oscillator manufactured by SiGe Semiconductor. It is optimized for applications in wideband communication networks, high frequency analog-to-digital conversion and low noise RF receiver systems. It is designed using a high performance 0.18um SiGe silicon process and contains a mixed signal frequency synthesizer, a sine wave oscillator, an active ring oscillator and an 8-bit digital frequency tuning control register.

PURE SN is designed to generate highly accurate and stable sine waves in the frequency range of 350MHz to 5.5GHz. The frequency resolution and accuracy of PURE SN devices can be set to 12 bits, providing a frequency resolution of 32.768Hz. This resolution is especially useful in applications where ultra low phase noise and low jitter are required.

The working of PURE SN oscillators is based on the concept of digital frequency tuning. A sine wave oscillator in the chip generates a stable sine wave, while an active ring oscillator is used to control the frequency of the wave. The frequency of the sine wave is then adjusted by the 8-bit digital frequency tuning control register which enables fine tuning of the frequency resolution. This enables precise tuning of the output signal with no additional phase noise or jitter.
