Oscillators are the electronic devices that generate periodic alternating currents over a wide range of frequencies. They are grouping of two major components—an amplifier and a feedback loop. SIT8208AI-2F-25E-12.288000T is one of the oscillators, suitable for receivers, transmitters and other frequency-dependent circuits, part of a signal chain.

SIT8208AI-2F-25E-12.288000T, as a kind of oscillator, has wide range of application fields. Firstly, it is widely used in many wireless communication systems, not only limiting to GSM, CDMA, UMTS and WLAN application, but also employing in LMDS, MIMO and other new access equipments. Secondly, it is used for SDR systems requiring instant-on/fast switching performance in the applications including base station, passive surveillance, spread spectrum communication and wireless LAN. Thirdly, it can be applied in any terrestrial and satellite radio frequency system.

The main working principle of SIT8208AI-2F-25E-12.288000T can be simply divided into three parts, one of which is the Variable Frequency Oscillator (VFO). A VFO is a L-C oscillator that can be manually tuned across a wide range of frequencies. The output of this oscillator is amplified by an amplifier and then fed back to the input through a feedback loop. By adding a stable reference voltage, the frequency output of this oscillator can be varied.

In the second part, the amplifier is used to amplify the VFO output voltage and current. It has a high frequency response, suitable for broadband applications. The last part is the feedback loop, used to adjust the phase of the voltage to match the phase of the input signal. This loop also provides a small amount of negative feedback, which can reduce the gain of the amplifier. This can improve linearity and reduce distortion.

In summary, SIT8208AI-2F-25E-12.288000T is a type of oscillator with wide application fields, mainly used in wireless communication systems, SDR systems, and terrestrial and satellite radio frequency systems. Its working principle involves the Variable Frequency Oscillator, amplifier, and feedback loop.
