SIT8208AI-82-25E-33.333000X Application Field and Working PrincipleOscillators are electrical or electronic devices that generate a repetitive and periodic alternating current waveform. This device, in particular, is a member of the SIT8208 package of numerical controlled oscillators (NCO). The product is designed to generate an accurate fixed frequency or voltage output offset from the input signal.The SIT8208AI-82-25E-33.333000X is one such NCO. It is composed of a Crystal Oscillator, Modulator Circuit and an Amplifier. This specific NCO has a wide range of operating frequencies and can operate from around 0.5 Hz to 25 MHz, making it suitable for applications from low to ultra-high frequencies.The device is designed to generate a sinusoidal output from an applied digital input signal and is typically specified by an input frequency, a voltage, or no load current. Due to its high frequency output stability, the SIT8208AI-82-25E-33.333000X is ideal for precision wireless communication systems, 3G/4G/5G cellular networks, RF and satellite communication networks, and other telecommunication applications. It can also be used in test and measurement equipment, military electronics, and industrial control systems.The internal operating principle of the NCO is based on an electrical resonant circuit, such as a quartz crystal or piezoelectric material, and an electronic feedback oscillator amplifier circuit. The NCO uses a voltage-controlled oscillator (VCO) circuit to accurately generate a fixed, repetitive waveform. This waveform is then shaped to the desired output waveform by the use of an external filter system. The NCO also employs a modulation circuit to convert a low-frequency digital input into a high-frequency waveform with extreme precision. This is achieved by modulating a higher frequency resonant circuit with the low-frequency signal from the modulator. The higher frequency signal is then amplified and tuned to the desired output frequency and passed through an external filter system.The accuracy of the output frequency generated by the NCO is greatly improved compared to that of a simple voltage-controlled crystal oscillator. This device is suitable for applications that require high accuracy clocks and reference source signals. The typical output is as low as 10-15 ppm, which is more than sufficient for most applications.In conclusion, the SIT8208AI-82-25E-33.333000X is a member of the SIT8208 package of numerical controlled oscillators. This device is suitable for a wide range of applications and offers high frequency output stability. It is ideal for precision wireless communication systems, 3G/4G/5G cellular networks, RF and satellite communication networks, telecommunication applications, test and measurement equipment, military electronics, and industrial control systems. It is suitable for applications that require high accuracy clocks and reference source signals, as the typical output is as low as 10-15 ppm. The internal operation of the NCO is based on an electrical resonant circuit and an electronic feedback oscillator amplifier circuit.
