552AD000812DGR

Pin configurable/selectable oscillators (such as the model 552AD000812DGR) are frequency control devices that enable users to adjust or customize the frequency or oscillation speed output of a circuit or system. They offer users the flexibility to select among multiple pre-defined frequencies or to adjust a frequency within a specified range, depending on the parameters of the application.

Pin configurable/selectable oscillators are typically used in consumer electronics, microwave communications, industrial control, and medical instrumentation systems. They have the ability to offer users an easy and efficient way to control the frequency and timing of circuits, and enable engineers to select different frequencies in different applications.

The 552AD000812DGR is a pin selectable oscillator that offers a frequency range from 3.57945MHz to 33.78MHz, with a 0.00000001Hz resolution. This model is designed for use in systems with applications requiring wide frequency selection, such as frequency modulation (FM), time division multiplexing (TDM), and time division multiple access (TDMA) systems.

The 552AD000812DGR operates by way of a two-part approach. First, a voltage is applied to a control pin to select the desired frequency. Second, an external voltage controlled resistor (VCR) or digital-to-analog converter (DAC) is used to fine-tune the output frequency. The 552AD000812DGR can be powered with a single +5VDC voltage and can manage a maximum supply current of 15mA.

The 552AD000812DGR consists of several key components that enable it to achieve such high-performance. These include a voltage-controlled oscillator (VCO), prescaler, frequency counter, filter, buffer, and PLL (phase-locked loop). The VCO uses an external resistor and capacitor to control the frequency, while the prescaler divides the output of the VCO by an integer value to provide an accurate frequency output. The frequency counter measures the frequency of the output signal and provides feedback to the PLL circuitry via a voltage-controlled resistor (VCR). The filter and buffer are used to provide isolation between the PLL and the output signal, and to reduce any noise or distortion.

The 552AD000812DGR provides a wide range of applications and enables users to quickly and efficiently configure different frequency outputs to meet any application requirements. The device is also well suited for use in mobile communications, digital signal processing (DSP) applications, and automotive systems.
