353TB3C27BR

Oscillators serve a variety of purposes in many electronic circuits, from the humble pendulum design that has been in used for hundreds of years to the most advanced digital systems. The 353TB3C27BR oscillator is a TTL (Transistor-Transistor Logic) oscillator designed for use in a variety of systems. It is designed to oscillate at frequencies between 4 and 10 MHz, and offers high stability and accuracy. This article will explain the application fields and working principles of the 353TB3C27BR oscillator.

Application Fields

The 353TB3C27BR oscillator is particularly well suited to applications that require high stability and accuracy, combined with a wide range of operating frequencies. It is particularly useful for clock sources, timing circuits, and frequency synthesizers. Systems, such as cellphone base stations, RF communications systems, and satellite receivers, utilize the 353TB3C27BR oscillator for its superior accuracy and stability. It is also well suited for consumer electronics applications since it does not require an expensive crystal, and therefore offers lower costs.

Working Principle

Although the exact specifics of the working principle of this oscillator may vary slightly from manufacturer to manufacturer, the general principle is the same. The 353TB3C27BR is a CMOS version of the popular TTL oscillator, meaning it has been designed to operate at much lower power levels. It consists of an inverting amplifier circuit that provides feedback to the input stage, forming an “oscillator” circuit. The amplifier has a frequency-determining resistor and a capacitor connected in the feedback loop of the amplifier.

The capacitor charges each time voltage is applied to the input of the amplifier and the resistor determines the rate at which the capacitor is charged. When the voltage level across the capacitor reaches a certain level, known as the “threshold voltage”, the amplifier switches states. This produces an output pulse. The frequency of the output pulse is determined by the combination of the capacitor and resistor, and can be adjusted if necessary.

The feedback loop also helps to maintain the frequency of the oscillations, since any changes in the capacitor and resistor values will cause the output pulse to change in frequency. This helps to ensure accuracy and stability, since the oscillator is self-regulating. Additionally, the low power requirements of the CMOS version of the oscillator makes it well-suited for applications where long battery life is a requirement.

Conclusion

The 353TB3C27BR oscillator is designed for applications requiring high stability and accuracy, combined with a wide range of operating frequencies. It is a CMOS version of the popular TTL oscillator, making it well-suited to applications where low power is a key consideration. The oscillator operates on a feedback loop, making it self-regulating and helping to ensure its accuracy and stability. The wide range of applications for this oscillator, from consumer electronics to satellite receivers, make it an ideal choice for a variety of systems.
