Programmable Oscillators are a type of oscillator which can be programmed to generate signal frequencies with high accuracy. One such device is the SIT9003AI-2-18EO, an integrated Programmable Oscillator.

Application field

The SIT9003AI-2-18EO is ideal for Analog to Digital Converters (A/D) and Digital to Analog Converters (D/A) as well as frequency multiplexers and demultiplexers in communications systems and multimedia applications. It is also used for clock and data recovery applications, digital tuning for radio and TV systems, and as a digital signal source for clock and data distribution networks.

Working principle

The SIT9003AI-2-18EO has an in-built programmable oscillator that allows frequency to be adjusted very accurately. This oscillator is based on an innovative frequency divider principle that uses a capacitor to divide the output signal frequency. The capacitance of this capacitor is adjustable, which allows very precise results to be obtained. This divider is driven by a fast, low-power linear oscillator, which is optimized for both frequency accuracy and low current consumption.

The SIT9003AI-2-18EO also features a phase-locked loop for clock synchronization. This phase-locked loop is designed for low jitter, providing high accuracy and good phase noise performance over a wide frequency range. Additionally, a voltage-controlled oscillator can be used to program the SIT9003AI-2-18EO to generate a wide range of signals. The device also has an output divider stage, which can be used to divide the output frequency, allowing the user to generate different signals that are synchronized to the main clock source.

In addition to its programmable oscillator, the SIT9003AI-2-18EO has a wide range of features designed for enhanced performance and convenience. These include an integrated power-delivery system, a low-noise reference clock oscillator, and a wide range of power-saving modes. The device can also be programmed via an I2C interface or via a 4-wire serial SPI interface.

The SIT9003AI-2-18EO is a highly accurate and efficient programmable oscillator with features designed for a wide range of applications. Its low power consumption and wide frequency range make it suitable for a variety of applications. Furthermore, its integrated power delivery system, low-noise reference clock oscillator, and wide range of power-saving modes provide enhanced performance and convenience in a wide range of applications.
