DSC2010FI1-A0003T

Pin Configurable/Selectable Oscillators, such as the DSC2010FI1-A0003T, offer more flexibility and improved performance while canceling the need for expensive crystal characterization. Pin configuration/selection oscillators eliminate extra components, such as external capacitors and inductors, and allow the same oscillator to accommodate a wide range of frequency requirements. They provide a simple, efficient, and cost-effective solution for applications that require high-frequency resolutions.

Application Field

DSC2010FI1-A0003T is a pin configurable/selectable oscillator specifically designed for portable devices such as cell phones, PDAs, and digital cameras. The device contains three different frequency settings and is ideal for applications that require a wide range of frequencies, including GSM, EDGE, and UMDX. This type of oscillator may also be used in other frequency-sensitive applications such as RF communication equipment, medical equipment, and consumer electronics.

Working Principle

The DSC2010FI1-A0003T oscillator utilizes a special pin configuration/selection mechanism that allows it to operate in nine different operating modes. The output frequency is determined by the combination of two primary pins: the input pin and the output pin. These pins are connected to a high-precision resistor ladder network, and the resistor network is connected to the oscillator’s output. By adjusting the resistance value between the two primary pins, the frequency of the oscillator can be changed.

To ensure stability, a special temperature compensated crystal oscillator (TCXO) is used. The TCXO utilizes a temperature compensation circuit to reduce the frequency error caused by changes in temperature. As the oscillator is adjusted, the frequency will shift gradually to a stable frequency level. In addition, the oscillator’s internal circuit also provides a fixed output load impedance setting that can be adjusted to match the required output load requirements.
