Programmable oscillators are rigidly-controlled frequency sources that are programmable through different methods based on the specific technology used. They are one of the most popular frequency control solutions used to generate up to millisecond-accurate signals with reliable repeatability and high resistance to temperature fluctuations. The SIT8008AIR3-25E is a programmable oscillator that is commonly used in a wide range of applications.The SIT8008AIR3-25E is a quartz-crystal-based oscillator that is well-suited for applications that require precise, low-jitter timing signals. It is available in an industry-standard ,3-inch-square package and is powered through a 3.3V supply voltage. This oscillator is designed to operate at frequencies up to 25MHz and it features excellent thermal characteristics and short cycle to cycle jitter. As a result, it is well-suited for frequency-control applications in consumer electronics, medical equipment, and aerospace systems.The SIT8008AIR3-25E oscillator uses a fixed quartz crystal and an external resistor to generate its frequency output. The crystal functions as an electrical circuit that will oscillate at a fixed frequency when excited by an electrical current. The frequency output of the crystal is then controlled by an external resistor, which adjusts the phase and frequency of the oscillations.The SIT8008AIR3-25E features a programmable phase-locked loop (PLL) to further improve the stability of the oscillator’s frequency output. The PLL works by constantly monitoring the phase and frequency of the oscillations and making small adjustments in order to maintain the desired frequency. This ensures that the oscillator can maintain its frequency stability even when subjected to temperature fluctuations or other environmental changes.The SIT8008AIR3-25E also features a built-in programmable digital delay line (DLL), which allows the frequency output to be precisely programmed or adjusted by the user. The DLL uses a damping algorithm to eliminate any dead-band or noise that may be present in the frequency output. This ensures that the oscillator can operate with minimal jitter, even when subjected to high-speed signals or cuts in the supply voltage.The SIT8008AIR3-25E is a highly reliable and precise oscillator, making it an ideal choice for a variety of applications. Its small size and excellent thermal characteristics make it well-suited for use in high-temperature environments, while its short cycle-to-cycle jitter and low power consumption make it the perfect solution for power-sensitive applications. In addition, its built-in DLL and PLL technologies make the SIT8008AIR3-25E an ideal choice for applications requiring precise and reliable frequency-control solutions.
