DSC2033FI2-F0003T Pin Configurable/Selectable Oscillators

Application Field

The DSC2033FI2-F0003T pin configurable/selectable oscillators have been developed for Standby applications which need to switch between an oscillator frequency and an external clock sourced from an SoC to save power. The application area of the oscillators is Embedded, Automotive and IoT applications. Additionally, they are ideal for Portable, Medical, AV and Home Automation as well as many others.

Working Principle

DSC2033FI2-F0003T pin configurable/selectable oscillators are based on a revolutionary new technology for low power applications that use an oscillator with a selectable external control pin for clock synchronization. The control pin which can be either a logic input or an external clock source is used to select the source of the oscillator’s clock signal, either from the oscillator or from the external source. When using the external clock, the oscillator frequency is locked to the frequency of the external clock and the oscillator is placed in a low power state. When the external clock is removed, the oscillator will automatically switch back to an internally generated frequency.The pin configurable/selectable oscillators have integrated circuits that enable them to detect the presence of an external clock and switch between frequencies accurately and in a very short time (sub nanosecond times). They also have built-in voltage regulation to protect the crystal from excess voltage and further reduce power consumption.DSC2033FI2-F0003T is designed to give designers a low-cost, low-power and easy-to-use solution for their oscillator needs .The oscillators offer excellent phase jitter performance (2.1ps RMS @ 20MHz) and long-term stability over temperature and supply. For applications that need greater flexibility, the pin configurable/selectable oscillator supports two separate pin configurations for the control pin, one for crystal oscillators and the other for clock synchronization.

Conclusion

The DSC2033FI2-F0003T Pin Configurable/Selectable Oscillators from DSC Corporation offers an ideal solution for Standby applications that need to switch between a selectable oscillator frequency and an external clock sourced from an SoC. The oscillators have superior phase jitter performance and integration of voltage regulation to protect the crystal from excessively high voltage. With their easy to use solution and low cost, they make an ideal choice for many embedded, automotive and IoT applications.
