Oscillators

Oscillators are types of electronic circuits that produce a regular, repetitive signal such as a sine wave, square wave, triangle wave or a sawtooth wave. They have been widely used in many applications including communications, computing, entertainment, power control and so on. Oscillators are essential components in a wide variety of modern electronic systems, including radio receivers and many forms of electronic music instruments.

SIT8208AI-31-33E-25.001875T application field and working principle

The SIT8208AI-31-33E-25.001875T is an oscillator widely used for applications in radio systems. It serves as an intermediate frequency oscillator in both mobile phones, and wireless communications systems. This oscillator has a low voltage operation with low jitter, and it is highly stable through tight temperature range. It has a frequency range of 24.5975MHz to 48.79 MHz, and an additional tuning range of up to 25 MHz. It is capable of outputting a sine wave with a low phase noise. It provides a power output of up to 2.5mW and low phase noise of -165dBc/Hz at 10kHz offset.

The working principle of the SIT8208AI-31-33E-25.001875T oscillator is based on the use of a voltage-controlled oscillator (VCO). This oscillator utilizes a constant amplitude sinusoidal voltage as its input signal. The generated signal then passes to the output stages, where feedback is coupled to the oscillator’s control voltage port. This control voltage is positive when the output signal is increasing in frequency and negative when the output signal is decreasing in frequency. By controlling the control voltage, the frequency of the output signal can be varied in a linear fashion. This allows the SIT8208AI-31-33E-25.001875T oscillator to generate signals with a range as identified above while maintaining tight phase noise performance.

The SIT8208AI-31-33E-25.001875T oscillator also utilizes an integrated high-performance PLL loop filter that helps reduce the noise present at the output. This PLL improves the phase noise performance of the oscillator and reduces the effect of broadcast interference and jamming. Additionally, the SIT8208AI-31-33E-25.001875T oscillator incorporates a power-down detection circuit that can shut down the oscillator when there is no supply voltage applied, thus reducing power consumption.

The SIT8208AI-31-33E-25.001875T oscillator is well-suited for applications such as FM transmitters, wireless communication systems, navigation systems, radio receivers, and more. It features a wide frequency tuning range with excellent phase noise performance, and is also very reliable and cost-effective.
