Oscillators: 536BB312M500DGR Application Field and Working Principle

Oscillators are electronic circuits that create a periodic electronic signal, usually a sine wave or a square wave. Oscillators are used in many electronic circuits, including radio-frequency transmitters, receivers, and amplifiers. The 536BB312M500DGR oscillator is a high-performance, low-voltage precision oscillator/microprocessor digitally-controlled crystal oscillator (DCXO) for communication and instrumentation equipment from among those offered by DATA DEVICE Corporation (DDC).

Application Field of 536BB312M500DGR Oscillator

The 536BB312M500DGR oscillator’s application field includes communications, system control, instrumentation, medical imaging, defense, and petrochemical. It is ideal for communications equipment, such as mobile systems, base stations for GSM/GPS/WCDMA, power amplifiers, and dental and x-ray imaging equipment.

Working Principle

The 536BB312M500DGR oscillator is a precision voltage-controlled oscillator (VCO) that uses a quartz crystal in conjunction with an electronic circuit to generate an electrical signal. The quartz crystal vibrates at a specific frequency when energized with an AC signal. The electronic circuit then amplifies the signal and feeds it back to the quartz crystal, keeping it vibrating at the same frequency. When the quartz crystal vibrates, it generates an electrical signal that is used to control the frequency of the oscillator.The 536BB312M500DGR oscillator is a microprocessor-controlled crystal oscillator (MCXO) that uses a 32-bit microcontroller, along with temperature sensors and a voltage reference, to control the frequency of the oscillator. The microcontroller monitors the quartz crystal frequency and adjusts the voltage applied to the quartz crystal to obtain the desired frequency. The frequency is adjusted by the microcontroller based on the temperature, voltage, and other parameters.

Advantages

The 536BB312M500DGR oscillator has a number of advantages over conventional crystal oscillators. These include low power consumption, high stability, wide operating temperature range, and excellent phase noise performance. The oscillator has a wide operating frequency range from 10 to 500 MHz, and a fast start up time of less than 5 milliseconds. Its temperature stability over the range of 0 to 50C is excellent, with less than +/- 2ppm. This oscillator is suitable for high-volume production applications, as it is RoHS compliant, and consumes only 2mA of current.

Conclusion

The 536BB312M500DGR oscillator is a high-performance, low-voltage precision oscillator/microprocessor digitally-controlled crystal oscillator (DCXO) offered by DATA DEVICE Corporation (DDC). It is suitable for communication and instrumentation applications, providing low power consumption, high stability, wide operating temperature range, and excellent phase noise performance. Its wide operating frequency range and fast start up time make it ideal for high-volume production applications.
