Pin Configurable/Selectable Oscillators – DSC2044FI1-H0006 application field and working principle

ThePin Configurable/Selectable Oscillators (PCSO) are a type of oscillator that utilizes a selectable frequency range to achieve unique setpoints and configurations. These frequency ranges are typically marked as F1, F2, F3 and F4. This frequency range selection option is used to select a single frequency as the setpoint, or a range of frequencies as the setpoint. The PCSO can be adjusted to accommodate various types of applications, allowing the user to select an optimum frequency range for the application at hand.The DSC2044FI1-H0006 PCSO from California Micro Devices is a high frequency oscillator that provides both a high frequency selectable frequency range and a low frequency selectable frequency range for the application. It operates in the frequency range of 500 kHz to 1.5 GHz. It is available in an 8-lead ceramic QFN package and operates on 1.8 V and 3.3 V supply voltages.The DSC2044FI1-H0006 PCSO utilizes a patented Pin Control Protocol (PCP) to configure the frequency range. This is done by changing the frequency range selection input pins. The selected frequency range is indicated by four LED’s, located on the package. By setting the frequency range selector pins, the frequency range output is set.The working principle of the DSC2044FI1-H0006 is based on the Resonance Frequency Control Technology, or RFC. RFC works by adjusting the frequency at which the oscillator vibrates, so that it reaches the desired frequency. This is accomplished by controlling the frequency at which energy is injected into and extracted from the resonant circuit. The frequency of the oscillator is regulated by a resonant circuit, consisting of an inductor, a load capacitor and a parallel feedback capacitor. The resonant frequency of the oscillator is determined by the load capacitor, which is in turn controlled by the value of the parallel capacitor, which can be adjusted with the PCP control pins.The DSC2044FI1-H0006 PCSO operates over a wide temperature range of -40°C to + 85°C, making it suitable for applications in harsh environments. The device also has a low power consumption of only 7mW, making it suitable for battery operated applications. The oscillator has a high frequency stability of +/-15ppm and a wide frequency range selectable in 1kHz increments.The DSC2044FI1-H0006 PCSO is ideal for applications requiring a wide frequency range, frequency stability and low power consumption. These include automotive entertainment systems, security cameras, automated control systems, gaming systems, healthcare devices and more.
