Classified as an Oscillator, the SIT8209AC-G3-28E-133.333000X is an integrated timing component used to generate precise clock signals for various digital systems. It offers low skew, low jitter performance, high frequency stability, and excellent longterm reliability.

Applications for SIT8209AC-G3-28E-133.333000X include, but are not limited to, microprocessor clock generators, DDR memory clocks, local area network (LAN) applications, and general communications applications. It is also suitable for various consumer applications like DVD players and routers.

The interior of the SIT8209AC-G3-28E-133.333000X oscillator is composed of an amplitude and frequency tuning circuit, a temperature-compensated oscillator (TCXO), an oscillator circuit, a clock circuit, and a frequency-adjustment circuit. By combining these components together, the oscillator can generate a precise clock signal with high frequency stability and long-term reliability.

The frequency tuning circuit is responsible for producing a constant clock signal with a specific frequency. This is achieved by adjusting the oscillator’s frequency using a crystal or resonator and the frequency adjustment circuit. The temperature-compensated oscillator (TCXO) maintains the oscillator’s frequency stability even when the outside temperature changes. The oscillator and clock circuits provide a signal with a high level of accuracy by exploiting the essential properties of the TCXO.

The SIT8209AC-G3-28E-133.333000X oscillator utilizes a phase-locked loop (PLL) circuit which drives a crystal oscillator or resonator to create a clock signal with a high degree of accuracy and stability. It also uses a frequency-adjustment circuit to adjust the oscillator’s frequency and correct any drift over time. The frequency-adjustment circuit consists of a digital-to-analog converter (DAC) that converts a digital input signal into an adjustable voltage signal.

The output signal of the SIT8209AC-G3-28E-133.333000X oscillator is then sent to the clock circuit, which is a complex phase detector, low-pass filter, and voltage-controlled oscillator (VCO). The clock circuit is responsible for producing a precise clock signal with low jitter and low skew, while the VCO is responsible for generating a clean signal with a high frequency. This signal is then sent to the frequency-adjustment circuit where it is regulated by the DAC.

The output of the SIT8209AC-G3-28E-133.333000X oscillator is an accurate and precise clock signal that meets the requirements of modern digital systems. Its low jitter and low skew performance, combined with high frequency stability and excellent longterm reliability, make it an ideal choice for a variety of digital systems.
