Pin Configurable/Selectable Oscillators offer a way of adjusting the frequency range of a given oscillator to within a defined bandwidth. In some cases, this can be done by changing the capacitance or inductance of a resonator, while in others it can also be accomplished using programmable digital logic. The DSC2010FI2-A0017 is an example of the latter case, providing an adjustable range of output frequency from one hertz to 33.75 MHz.

The DSC2010FI2-A0017 is a CMOS digital oscillator designed specifically for use in embedded systems. It is designed to produce low-noise frequencies, with a very low current consumption. The oscillator produces a square wave output, and the user can choose from a range of frequencies from one hertz to 33.75 MHz. The frequency is selected by setting the pin configuration, as detailed in the datasheet.

The device consists of a high-speed oscillator abstracted by a voltage-controlled delay cell. The oscillator is enabled by applying an input voltage of 3.3V to its oscillation enable pin. The output frequency is determined by the delay cell, which adjusts its own delay in response to an input control voltage. This input control voltage is programmed by setting the pins of the oscillator, which determine the amount of current sourced to the delay cell. The resulting delay is then used to set the oscillator frequency.

The device includes an internal temperature compensation circuit, which improves its stability. This tempco circuit compensates for various environmental factors, such as temperature variations and process noise. The compensated oscillator frequency can easily be adjusted by the external adjustment inputs, which can control the frequency with a resolution of 0.01%.

The DSC2010FI2-A0017 can be used in various applications, such as frequency synthesis, broadcast radio, television, radar, and communications systems. It can also be used for timekeeping in digital systems. The oscillator is suitable for operation in harsh environments, with an operating temperature range of -40℃ to +85℃.

The DSC2010FI2-A0017 makes a versatile and inexpensive choice of oscillator for embedded systems. Its low power consumption and wide frequency range make it an ideal choice for use in a variety of different applications. The ability to easily adjust the frequency makes it well suited for use in frequency-based applications, while its low-noise characteristics make it a good choice for use in communications systems.
