Pin Configurable/Selectable Oscillators: 552BE000591DGR

Pin Configurable/Selectable Oscillators are electronic components and oscillators that enable the user to select one of several available output frequencies to suit their particular application requirements, usually based on the number of pins they have which are assigned to different frequencyor configuration options. The 552BE000591DGR is a configurable oscillator containing two separate power supply pins, an enable pin, and a selectable frequency pin, allowing users to select between eight different output frequencies.

Application Field

The 552BE000591DGR is a two output, low power, crystal oscillator that is ideal for timing requirements of a wide variety of applications, including those with low-power, battery-operated or portable devices, such as medical and health care equipment, wearables, industrial instrumentation, consumer applications, as well as wireless and smart home devices. The pin configurable mode further flexes the design and allows for varying application frequencies.

Working Principle

The 552BE000591DGR utilizes a low power, crystal-based oscillator, with a pair of integrated capacitors to generate square-waves at selectable frequencies over a temperature range between -40 to 85 degrees Celsius. The oscillator operates using two possible power supply pin configurations, using either a single supply of 1.8 to 3.6 Volts, or dual supplies of 1.2 to 3.6 Volts. The internal capacitance and configuration of the device act as a filter, enabling the selection of output frequency between 45 kHz and 144 kHz, with a maximum momentary variation of ±200 ppm ranging from -40 to 85 degrees Celsius.

Pin Configuration

The 552BE000591DGR includes two power supply pins, enabling the user to either select a single supply of 1.8 – 3.6 Volts, or dual supplies of 1.2 to 3.6 Volts. An enable pin is provided that allows the user to put the oscillator in active or inactive mode, and a selectable frequency pin provides the user with the ability to select between 8 different output frequencies. Finally, the output pins of the device are connected internally to the crystal oscillator on the package, providing a buffered drive of the output signal.

Conclusion

The 552BE000591DGR provides designers with an easy to implement, configurable, low-power oscillator solution, with options to use a single or dual supply voltage, an enable pin, and a selectable frequency pin. This device is an ideal solution for a wide variety of applications that are looking for a configurable oscillator, with a temperature range of -40 to 85 degrees Celsius and very precise frequency selection.
