Pin Configurable/Selectable Oscillators are devices designed to provide versatile and comprehensive frequency control of electrical signals. While traditionally oscillator devices delivered fixed frequency output, pin configurable oscillators offer the ability to select an appropriate signal frequency from a wide range of options by simply configuring the oscillator\'s pins. In this paper we discuss the 554AD002399DG oscillator, its application fields and its operating principle.

Application Field of 554AD002399DG Oscillator

The 554AD002399DG oscillator offers a wide range of application fields. Its output frequency range can vary between 0.8 MHz to 44.7 MHz and its versatile device design makes it a suitable choice in applications like clock/data recovery, radio transceivers, and general purpose system synchronization among many others. It can also be used as a reference signal source in RF transmitters, telecoms apparatuses or as a local oscillator for microwave frequency synthesis.

Working Principle of 554AD002399DG Oscillator

The 554AD002399DG oscillator operates on the principle of voltage-controlled crystal oscillator technology. A quartz crystal is used as the resonator of the oscillator and the output signal is generated from the vibration of the crystal. The crystal is maintained in a state of known exact resonance via a control voltage, thus creating the desired signal. This signal is then amplified, filtered, and output as the oscillator signal.

The oscillator\'s frequency can be adjusted by changing the values of two pin-configured resistors, R1 and R2. Raising the value of R1 lowers the oscillator frequency while lowering the value of R2 increases the oscillator frequency. These two resistors also function to reduce system noise and maintain the crystal frequency.

Another pin, either G mod or LP/XTAL, is used to set the control voltage of the crystal, thus influencing the oscillator\'s frequency and stability. G-mod is used to set the oscillator in the low-frequency mode by applying an external current to it and LP/XTAL is used to set the oscillator in the high-frequency mode by applying a voltage to it. The high-frequency mode provides better frequency stability with G-mod operating in standby mode.

Conclusion

The 554AD002399DG oscillator is a versatile device capable of producing an adjustable frequency output ranging from 0.8 MHz to 44.7 MHz. It functions on the principle of voltage-controlled crystal oscillator technology and its operation is greatly influenced by two pin-configurable resistors, R1 and R2, as well as either the G-mod or LP/XTAL pin. The 554AD002399DG oscillator can be used in a variety of applications and is one of the most cost-effective solutions for providing clock/data recovery, system synchronization or frequency synthesis.
