Pin Configurable/Selectable Oscillators

The 552AD000491DGR pin configurable/selectable oscillator is a highly versatile device designed to aid in the implementation of critical timing requirements in a variety of applications.

This oscillator utilizes a combination of external pins and digital logic to allow for a wide range of frequencies to be obtained in a very small physical package. Specifically, the 552AD000491DGR consists of a programmable frequency source, a built-in crystal oscillator, and digital logic to control an output frequency that is selectable from multiple pre-programmed frequencies. The frequency is chosen using three pins, which can be used to select from a table of up to 16 pre-programmed frequencies.

The 552AD000491DGR is ideal for designs that require flexibility in frequency selection, such as those with multiple frequencies or protocols. By combining the crystal oscillator and digital logic into a single package, this oscillator provides a convenient way to integrate a wide range of frequencies into designs which are both cost-effective and reliable. This also makes implementation of design changes much easier due to the reduced complexity and shorter development cycle.

In addition, this oscillator is designed to be extremely reliable in noisy environments due to its robust design processes and the use of solid state components. Additionally, the device is tested against a variety of vibration, temperature, and shock ratings to ensure it operates reliably in demanding environments.

The 552AD000491DGR can be implemented in many practical applications, including consumer electronics, telecommunications, medical equipment, aerospace, military, automotive, and consumer audio/video. This device can be used as a precision timebase in clock synchronizers, embedded microprocessors and digital signal processors, real-time clock chips, digital thermometers, wearable medical equipment, satellite navigation systems, and many more applications.

The 552AD000491DGR offers many advantages over competitors. One of these advantages is the output frequency accuracy of its programmable frequency source. This ensures that the clock signal is stable over temperature, supply voltage, and process variation. The frequency synthesizers in the device also offer multiple selectable frequencies while also preserving stability. This helps reduce design complexity, shortens the development cycle, improves signal integrity, and reduces total cost. Finally, the oscillator allows for considerable frequency customization and can be quickly reconfigured to reduce downtime and minimize hardware replacement costs.
