Pin Configurable/Selectable Oscillators

Pin configurable/selectable oscillators are components which allow a user to select an oscillation frequency between two or more pre-determined frequencies using multiple pins on the oscillator. The oscillator is typically identified by its output frequency range, operating temperature and the number of selectable frequencies. The usually come in the form of dual in line packages, however various other package types are available.The 597PF000189DG is a pin configurable/selectable oscillator which has a frequency range from 9.6 to 160MHz and an operating temperature range of -40℃ to +85℃. It can be configured and tuned to one of five preprogrammed frequencies which include 9.6, 13.5, 19.2, 38.4 or 160 MHz. This oscillator is commonly used in a wide range of applications including automotive, industrial and consumer electronics.

Application Field

The 597PF000189DG is found in a variety of automotive and industrial applications. These include motor control, telecommunications and other industrial automation systems. The oscillator can also be used in consumer electronics, including television sets, DVD players and set-top boxes. It is also commonly utilized in gaming systems, such as PlayStation and Xbox.

Working Principle

The 597PF000189DG can be programmed to oscillate at one of five pre-selected frequencies. It does this by changing the capacitance on the load capacitor, which is controlled by an external resistor. This enables a user to select an oscillation frequency between two or more pre-determined frequencies.The oscillator has a voltage controlled oscillator (VCO) which is used to generate the output frequency of the oscillator. It is connected to a programmable load capacitor, which is controlled by an external resistor. This resistor allows the user to select one of the pre-determined frequencies.The output frequency of the oscillator is then determined by the capacitance of the programmable load capacitor. The capacitance of the capacitor is directly proportional to the external resistor, which allows the user to select the desired frequency.The oscillator also has an input buffer which is used to reduce noise and improve the accuracy of the output frequency. The output of the oscillator is also buffered, which helps to reduce power consumption and improve the stability of the output frequency.
