Pin Configurable/Selectable Oscillators

Pin configurable/selectable oscillators provide a simple and cost-effective way to select from a wide range of output frequencies. These oscillators are usually offered in a dual-in-line package, and feature two or more very stable, low noise outputs with settings of fixed or selectable frequencies. The M685-02-AM-AQ oscillator belongs to this family of oscillators.

Application Fields

The M685-02-AM-AQ oscillator is a quad frequency oscillator with a built-in selectable frequency. It is suitable for applications needing either an output frequency of 4, 8, 12 or 16 MHz. It is commonly used in four items that require a stable, accurate frequency output signal:

• GPS Navigation Systems
• Quartz Crystals for Timing
• Communication Systems
• Automotive and Industrial Applications

The device is also widely used in a variety of communication protocols, such as Bluetooth, Wi-Fi, RFID and Zigbee.

Working Principle

The M685-02-AM-AQ oscillator works by generating an oscillation at a set frequency. This frequency is modulated with a set of programmable logic elements (PLEs). Each PLE is programmed to turn on and off at specific times, resulting in a modulated frequency output. The frequency of the output of the M685-02-AM-AQ oscillator is determined by the state of the PLEs.The oscillator is composed of four main components: a quartz crystal oscillator and three PLEs, each of which can be programmed to produce a different frequency. The quartz crystal oscillator generates an oscillation frequency, and the three PLEs modulate this frequency, resulting in an output frequency that can be changed dynamically.The programming of the PLEs is done with the two control pins, the Clock and Data pins. The Clock pin determines when the PLEs switch states, and the Data pin is used to program the PLEs. The programming of the PLEs can be done during manufacture or in the field.

Conclusion

The M685-02-AM-AQ oscillator provides an easy and cost-effective way to select any of the four available frequencies. It is suitable for a wide range of applications, such as GPS navigation systems, quartz crystals used for timing, communication protocols and automotive and industrial applications. The device is composed of a quartz crystal oscillator and three programmable logic elements which can be programmed to produce a desired frequency. It is programmed with the two control pins, Clock and Data, and the programming can be done during manufacture or in the field.
