Pin Configurable/Selectable Oscillators

Pin Configurable/Selectable Oscillators are a type of oscillator that provide a compact solution for applications requiring specific programming capabilities. Utilizing a high-speed Digital-to-Analog Converter (DAC) and a CMOS-controlled Digital Oscillator (DO), these oscillators enable a wide variety of oscillator frequency, output voltage, and output format configurations. The 534MC000260DG is one such oscillator which makes use of three pins, two dedicated digital control pins, and a dedicated analog reference pin, to allow for easy configuration.

Applications

The 534MC000260DG is ideal for applications requiring a compact, easily configurable oscillator. The oscillator can be configured to produce a range of output frequencies, all within a relatively wide range of 1 Hz to 1.2 GHz. This makes the device ideal for RF applications, such as those found in mobile telecommunication systems and wireless networks. Additionally, with its wide range of output voltage options and customizable format, the oscillator is suitable for use in applications such as temperature sensors and MEMs motion sensors.

Working Principle

At its core, the 534MC000260DG consists of a CMOS-controlled Digital Oscillator (DO) and a high-speed Digital-to-Analog Converter (DAC). When the oscillator is started, the DO produces a square wave signal, which is then converted to an analog signal by the DAC. Through the use of three control pins, two dedicated digital control pins and one dedicated analog reference pin, the frequency and output voltage can be adjusted in a simple and efficient manner. The reference pin sets the voltage bias within the digital-to-analog converter, adjusting the output voltage of the oscillator. Meanwhile, the two digital control pins provide a user-configurable digital input which controls the output frequency of the oscillator. The combination of these two settings thus creates a wide range of output frequency and output voltage configurations.In addition to its configuration capabilities, the oscillator also features a low-power standby mode that allows the oscillator to consume far less power while still maintaining its configuration. This is done by using the two digital control pins to maintain the configuration settings while the DAC is in standby mode.

Conclusion

The 534MC000260DG is one example of a pin configurable/selectable oscillator that offers a compact, easy-to-configure solution for applications requiring precise frequency and output voltage configuration. Utilizing a digital-to-analog converter and digital oscillator, and with the aid of three control pins, the oscillator enables a wide range of frequency and voltage configurations. Additionally, the oscillator makes use of a low-power standby mode to reduce power consumption while maintaining its configuration settings. This combination of features makes the 534MC000260DG an ideal choice for a variety of RF and sensing applications.
