Programmable Oscillators: SIT8008AIE3-XXS Application Field and Working PrincipleProgrammable oscillators are electronic components developed to accept and respond to control signals externally by outputting signals at the desired frequency. Popular in applications such as portable devices and embedded systems, these oscillators have recently become the cornerstone of electronics engineering. One such example of a modern programmable oscillator is the SIT8008AIE3-XXS.Breaking down the name of the oscillator, “SIT” stands for “Sitronix Technology Corporation”, the Taiwanese manufacturing company who created the component. The “A” denotes that the component is located on the 4th row, 14th column of their catalog. “I” and “E3” represent the component’s internal product code and its iteration level, respectively. Finally, the “XXS” signifies that the component should be paired with a specific crystal reference oscillator.The SIT8008AIE3-XXS is designed to provide between 0.25 and 32 MHz of output frequency depending on the crystal reference oscillator attached to it. Like most programmable oscillators, the SIT8008AIE3-XXS is designed to respond to external control signals, allowing it to shift frequencies. The component also incorporates a low-power internal voltage regulator.The primary application of the SIT8008AIE3-XXS is as an audio clock for systems performing audio-related tasks, such as speaker dongles, game consoles, karaoke systems, and other consumer electronics. The component’s low power consumption allows it to fit comfortably in battery-powered applications. The component can also be used for general purpose frequency control applications in embedded systems, such as for controlling motors and communication peripherals. The working principle of the SIT8008AIE3-XXS can be broken down into three main stages. The first stage involves the reference oscillator, which receives electrical power from the device to be controlled and provides a reference signal based on its frequency. During the course of the second stage, the device will respond to an external signal (via a dedicated control/programming port) by adjusting the frequency of the internal oscillator to match the frequency of the reference signal. Finally, the output signal of the component will be sent outside of the device and used to control the specific peripheral at that frequency.The SIT8008AIE3-XXS is a great example of the modern programmable oscillator. Its low-power consumption, wide frequency output range and high accuracy make it an ideal choice for audio clock applications, as well as general embedded system frequency control. In addition, the component’s ability to easily respond to external control signals makes it well-suited for a variety of applications.
