Pin Configurable/Selectable Oscillators are a type of oscillator that allows users to choose from a range of operating frequencies, stability and input drive levels by quickly changing the configuration of the pins. The DSC400-0303Q0092KE2T is a nifty example of a pin configurable/selectable oscillator with a good range of frequency, stability and input drive levels available.

The DSC400-0303Q0092KE2T is a hermetically sealed oscillator with 4 pins suitable for +2V to +3.3V power supplies. It provides operating frequencies between 10MHz to 100MHz, with a frequency stability of ±100ppm over temperatures of -40°C to 85°C, and pullability of ±100ppm. Its input drive level (IDT) ranges from 2mA to 15mA, enabling the user to choose between a low current setting for a lower power consumption, or higher current for a higher power consumption.

The oscillator has a variety of applications including communications, meterology, navigation, instrumentation, petroleum, industrial and automotive. It is widely used in many high reliability and extreme environment applications such as weather and navigation systems, radar, satellite and missile guidance systems. It is also used in consumer electronic applications and has a good record for noise immunity.

The working principle of the DSC400-0303Q0092KE2T oscillator is based on the reverse transistor voltage control oscillator (VCO) circuit, and uses a resonator to generate the oscillatory output. The reverse transistor VCO circuit is essentially an amplifier with a feedback loop. In this oscillator the gain is set by the ratio between two feedback resistors which allows the user to choose between different frequency ranges. This output is then fed to a quartz crystal or ceramic resonator, which provides the accuracy of frequency stability, as well as a wide frequency range.

The oscillator is very robust and provides good frequency stability over temperature and power supply line changes. The user can easily choose from a range of operating frequencies, frequency stability, and input drive levels. A small change in the pin configuration of the DSC400-0303Q0092KE2T can greatly alter the output frequency and stability of the oscillator. This makes the DSC400-0303Q0092KE2T a great choice for various applications, where a wide range of frequency, stability and input drive levels are desired.
