Pin Configurable/Selectable Oscillators

Pin configurable and selectable oscillators are a type of electronically supplemented oscillator that can be customized, or configured, to meet specific needs. The types of configurable oscillators available are diverse, ranging from low frequency to RF to ultra-high frequency (UHF). Depending on the application, they may be configured to generate a pre-selected frequency, operate at a user-selected speed, operate in a variety of power conditions, have built-in phase-shift capabilities, and many more.

DSC400-0303Q0092KE1T Application Field and Working Principle

The DSC400-0303Q0092KE1T is a pin configurable/selectable oscillator designed for precision military and industrial applications. It is constructed with a low-profile, surface mount profile. This allows the oscillator to be used in a wide variety of high-density, miniature applications, such as medical devices, sensors, and RFIDs.

The oscillator operates on a frequency of 1GHz and offers the user a programmable frequency range of 9KHz to 900MHz, with a temperature stability of ±50ppm over a temperature range of 0°C to 70°C. The device is capable of operating at both single-ended and differential power supplies, making it suitable for a variety of system configurations. The voltage range is 3.3V to 5V.

The primary principle behind the operation of this oscillator is that an AC signal is generated by an inductor/capacitor (LC) circuit, with the oscillator’s output parameter affecting its frequency. The output frequency is determined by the capacitor, inductor, and resistive elements in the LC circuit. A Frequency Control Register (FCR) allows the user to program the output frequency of the oscillator. Additionally, the oscillator can be programmed with either a voltage control register (VCR) or a temperature control register (TCR), allowing for fine tuning of the output frequency.

The device offers several features for increased accuracy and reliability, such as Low Frequency (LF) Assist and Dithering Control. The LF Assist allows the oscillator to self-correct frequencies according to an applied reference voltage that is set to the LF Assist circuit. The dithering control increases the oscillator’s stability over a range of conditions and helps reduce jitter. The device is also RoHS compliant and has an operating life expectancy of 10 years.

In summary, the DSC400-0303Q0092KE1T is a highly-accurate pin configurable/selectable oscillator designed for a variety of precision military and industrial applications. It offers high frequency stability and versatility, along with several features for improved accuracy and reliability.
