Pin Configurable/Selectable Oscillators are devices that act as an electronic oscillator working on an adjustable frequency. The 554AC000311DG is equipped with a pin configuration selectable option for easy access to frequency outputs. It is ideal for applications such as digital audio, frequency division, medical devices, broadcast television and radio.

The 554AC000311DG offers a complete range of pin-configurable frequencies from 0.2 kHz to 8 MHz. The device is designed to have a very high degree of accuracy, minimal frequency drift and high reliability. The oscillator is rated up to 27.574 V operating voltage, making it suitable for a variety of applications. It also features very low power consumption and high stability.

The 554AC000311DG operates by using a pair of feedback loops. The first loop consists of an amplifier, a capacitor and an oscillator coupled together. The second loop is the reference oscillator, which is the reference frequency that the device uses to control the output frequency. The capacitors are used to tune the oscillator and the amplifier adjusts the reference frequency\'s amplitude. A resistor and a switch is used to adjust the output frequency according to the user\'s requirements.

In order to select the desired output frequency, the user must connect the appropriate pins on the device and open/close the switch. The device will then output the frequency designated for the specific output pin. This process can be repeated multiple times when updating the output frequency. The user can also use the digital input pins to select a pre-programmed frequency. This offers a more precise method of controlling the oscillator.

The 554AC000311DG also offers an optional external synchronization capability that allows the user to synchronize the output frequency to an external reference signal. An internal resistor is used to adjust the sensitivity of the external synchronization function, allowing the user to fine tune the synchronization process.

By utilizing a low power consumption and a high degree of accuracy, the 554AC000311DG has a wide range of application fields. It is widely used in communications, instrumentation, medical, automotive and aerospace systems. The adjustable frequency range and output frequency stability make it ideal for products such as frequency dividers, digital audio systems and cellular base stations. The synchronization capability makes it suitable for test and measurement equipment as well.

The 554AC000311DG is a capable device for applications where a pin-configurable, selectable oscillator is required. Its adjustable frequency range, low power consumption and highly stable output frequency allow it to be used in a broad range of applications. In addition the external synchronization ability makes it an efficient choice for digital audio systems, broadcast television and radio and a multitude of other applications.
