It is also used in many industrial and automotive applications, including navigation systems, remote control systems and control systems.The SIT9002AC-18H33DB Programmable Oscillator features a range of output frequencies from 0.25MHz to 32MHz. It has an excellent jitter profile, which makes it suitable for high-clock frequency applications and can achieve low-jitter clocking requirements without external components. It also has excellent accuracy and stability over a wide operating temperature range, making it suitable for applications in extreme temperatures.

Working Principle

The SIT9002AC-18H33DB Programmable Oscillator uses a high-performance, low-cost oscillator module to generate a precise output frequency. The oscillator module consists of a voltage-controlled oscillator (VCO) and a phase-locked loop (PLL). The VCO generates an analog output signal at a frequency determined by its input voltage, which is determined by the phase-locked loop.The phase-locked loop consists of a phase frequency detector (PFD), a charge pump and a loop filter. The PFD compares the input signal frequency and the VCO output frequency and produces an error signal proportional to the difference between the two. The charge pump then amplifies the error signal and applies it to the loop filter, which filters out noise and passes only the applied signal to the VCO. This creates a feedback loop that maintains the VCO frequency at the desired output frequency.The SIT9002AC-18H33DB Programmable Oscillator also features an integrated programmable logic array (PLA) that allows the oscillator to be programmed to produce a predetermined frequency that is not available via the VCO. It also offers an external logic control signal input, allowing the oscillator to be remotely controlled.The SIT9002AC-18H33DB Programmable Oscillator is an ideal choice for applications requiring reliability, temperature stability, accuracy, low jitter and cost efficiency. In addition to its many applications, this oscillator is also excellent for use in radio transmitters, digital video receivers and mobile media players. It is a great choice for any project that requires precise timing.
