Pin Configurable/Selectable Oscillators

Pin configurable/selectable ( PCS ) oscillators are among the most widely used types of electrical timing devices in electronics today and are becoming more and more prevalent in the market. As their name suggests, these oscillators allow the user to configure and select the frequency of the oscillation from a range of presets. A good example of a pin configurable/selectable oscillator is the 552FD000270DGR, which allows for a wide range of different user-selectable frequencies.

What is the 552FD000270DGR?

The 552FD000270DGR is an oscillator made by Texas Instruments. It is a high frequency, narrow range, pin configurable/selectable oscillator with a single pin configuration and wide operating temperature range. It allows the user to select a frequency from a range of 4 to 27MHz, with an accuracy of -0.25% over the temperature range of -20 to +70C. The oscillator can operate in either crystal or ceramic media, depending on the user\'s preference. It also has low power dissipation and a low EMI, making it ideal for a wide range of applications.

Application Field

The 552FD000270DGR is suitable for a wide range of applications, from consumer electronics to industrial control and embedded systems. Some of its more common uses include frequency generation for microcontrollers, radio frequency tuning, clock synthesis for logic devices, and time-base synchronization for systems. It can even be used for the generation of high-frequency digital signals for communications systems.

Working Principle

When using the 552FD000270DGR, the user must first select a desired frequency from the available range. This is done by setting the voltage applied to the device\'s pin with a variety of methods, including voltage-controlled oscillators (VCOs), external capacitors, or other electronic components. Once a frequency is selected, the device will oscillate at the specified frequency and make use of crystal or ceramic media to provide the frequency stability.

Conclusion

The 552FD000270DGR is an excellent example of a pin configurable/selectable oscillator. It provides a wide range of user-selectable frequencies and a wide temperature range, making it suitable for a variety of applications. Its low power consumption and low EMI also make it a great choice for embedded systems. The user can easily configure and select the desired frequency, making it a versatile tool for many tasks.
