Oscillators are essential components used to generate timed electrical signals of regular frequency and amplitude, and SIT8209AC-31-33E-200.000000T is one of them. As a miniature SMD VXO, this oscillator provides a compact, cost-effective frequency stabilization solution for a variety of electronic applications ranging from computer peripherals and handheld devices to industrial automation and aerospace systems.

SIT8209AC-31-33E-200.000000T has a compact size and operates on a wide range of alternating current (AC) and DC down to 3.3 V. It has an excellent sinusoidal waveform with a frequency stability of ±50 ppm, low phase noise and good electromagnetic interference (EMI) performance when operated in electromagnetic environments. The internal circuitry of the oscillator provides first-order temperature compensation, which helps to ensure excellent frequency accuracy and stability over a wide temperature range.

The oscillator contains an oscillator circuit, an amplifier circuit, and a phase-locked loop circuit. The oscillator circuit produces an alternating sinusoidal wave with a certain frequency. The amplifier circuit amplifies the output signal of the oscillator and adjusts the amplitude. The phase-locked loop circuit is composed of a phase detector, a voltage-controlled oscillator (VCO), and a low-pass filter. The phase detector detects the phase difference between the input VCO output and the reference frequency. The VCO is used to convert the difference signal output from the phase detector into a frequency difference signal. The low-pass filter filters the frequency difference signal to adjust the VCO oscillation frequency to the same frequency as the reference frequency.

SIT8209AC-31-33E-200.000000T is ideal for applications where accurate frequency control is needed. It is especially suitable for embedded system designs, such as in digital signal processing (DSP) devices, wireless infrastructure equipment, and set-top boxes. It is also suitable for use in telecom base stations, cellular phones, IP cameras, and high-end consumer electronics to provide accuracy and stability in frequency patterns. Due to its precision and excellent performance, it is widely used in many industrial and commercial fields.
