Pin configurable/selectable oscillators are a class of oscillators that offer the option to be configured using pin selections so as to change their output frequency with ease. The particular oscillator that this article focuses on is the DSC400-0202Q0107KI1T, which is a temperature-compensated ultra-stable voltage-controlled oscillator (TCVCXO).

The DSC400-0202Q0107KI1T combines four unique technologies including temperature compensation to increase performance and stability, CSAC technology to reduce power consumption, and a DIP-Switch selectable frequency control to reduce system complexity. Its main application is for frequency control of wireless backhaul and data communication equipment, radar systems and next-generation radio transmitters. It is also suitable for use in base-stations and other telecom applications.

In order to understand and appreciate the working principle of the DSC400-0202Q0107KI1T, it is important to first understand its construction. This device consists of three independent components, namely a Temperature Compensated Crystal Oscillator (TCXO), a CSAC, and a DIP-Switch Selectable Frequency Control. The TCXO is the main oscillator and is responsible for producing the output clock signal. The CSAC is responsible for providing lower power consumption and improved stability. Finally, the DIP-Switch Selectable Frequency Control allows users to adjust the oscillator frequency to meet their needs.

The working principle of the DSC400-0202Q0107KI1T is based on the design of the temperature compensation circuit. This circuit utilizes a temperature compensated crystal oscillator (TCXO) which is temperature compensated on its output side by a negative temperature coefficient (NTC) resistor. This resistor has a value that is proportional to the temperature of the oscillator. As a result, as the temperature of the oscillator increases and decreases, the resistor value adjusts accordingly, thus compensating for the temperature and improving the output frequency accuracy and stability. In order to adjust the frequency of the oscillator, users can use the DIP-Switch Selectable Frequency Control.

In addition to temperature compensation, the DSC400-0202Q0107KI1T also features CSAC technology, which stands for “Computational Stability Analysis Control.” This technology helps to reduce power consumption and increase stability by controlling the output frequency in real-time based on calculations which are performed within the control circuit.

The DSC400-0202Q0107KI1T is a reliable, accurate, and low power consuming ultra-stable voltage-controlled oscillator that is ideal for use in wireless backhaul and data communications, radar, and next-generation radio transmitters. Its temperature compensation feature ensures excellent frequency stability over temperature, while the CSAC technology further improves stability and reduces power consumption. Furthermore, its DIP-Switch Selectable Frequency Control offers users the ability to adjust the output frequency so as to better suit their needs.
