Introduction to Oscillators

An oscillator is a device that generates a continuous periodic signal which is independent of other circuit elements within the device. Oscillators typically generate sinusoidal, triangular, or square waves with frequencies ranging from a fraction of a Hertz to several hundred Megahertz. They are used in a variety of areas, such as communications, instrumentation, automation, aerospace, consumer electronics, and medical equipment.

Uses of Oscillators

Oscillators are used to provide a steady, repetitive, predictable output signal used in a wide range of technologies such as clocks, alarms, and other timing circuits, satellite positioning, frequency hopping, phase-locked loops (PLLs), radio frequency (RF) circuits, digital-to-analog conversion, and many more. There are a variety of types of oscillators, such as Voltage Controlled Oscillators (VCOs), Crystal Oscillators, and Pulse Oscillators. Each type is designed to generate an output with a certain frequency and a certain shape of waveform.

The unit allows for an adjustable frequency range of 1.8 MHz to 120 MHz, and an output impedance of 50 ohms and constant impedance of 2K ohms. It features low total harmonic distortion, high linearity, high jitter tolerance, low power consumption, and high speed.

As a Clock Oscillator, the 353TB3C192T is used in many applications such as telecommunications, household electronics, etc. It is capable of generating both sine and square waves, and has a wide variety of stability options. It can be configured as a voltage-controlled oscillator, crystals oscillator, or an external clock source.

The 353TB3C192T utilizes a modified Pierce oscillator topology. This is a type of oscillator which uses a resonator, typically a quartz crystal, to produce a single-frequency signal. The oscillator is made up of an amplifier, a crystal resonator, and a feedback network. The crystal oscillator provides the feedback necessary for the amplifier to produce oscillations. The output frequency is determined by the crystal’s resonant frequency.

The 353TB3C192T features an extremely low power consumption of only 0.82 – 0.95 W, making it suitable for battery powered devices. It also features high linearity, with the THD (Total Harmonic Distortion) remaining less than 0.4 % up to 450 MHz. The jitter tolerance is also quite high, reaching 0.6ps RMS and 1.6ps peak-to-peak for a 28 kHz input.
