Oscillators are electronic devices that produce a continuous output signal, often a sine wave or square wave, at a fixed frequency. SIT8208AI-3F-18S-50.000000Y is an example of an oscillator, a versatile Programmable Oscillator with rich features and flexibility. Designers use these oscillators for a variety of applications in communications, timing and clocking, instrumentation, and consumer products.

Application Field

The SIT8208AI-3F-18S-50.000000Y is a combination temperature-compensated crystal oscillator (TCXO) and voltage-controlled oscillator (VCO) with digital frequency control. It is designed for applications which require a reliable, low-jitter, and universal clock source such as wireless backhaul networks and core telecom infrastructure. It is also applicable in broadband access, satellite communications, and consumer multimedia applications, such as voice over IP (VoIP). It offers the perfect balance between temperature stability and wide operational frequency range, with frequency range spanning from 10 MHz to 250 MHz.

Working Principle

The SIT8208AI-3F-18S-50.000000Y contains two independent circuits for frequency generation. One is a temperature-compensated crystal oscillator (TCXO) stage that uses a quartz crystal to generate a stable reference signal for the VCO stage. The TCXO is typically a fixed-frequency crystal oscillator with a wide temperature range and high stability over temperature. The purpose of the TCXO is to provide an initial frequency reference to the VCO stage.

The VCO stage is the second circuit of the SIT8208AI-3F-18S-50, and it provides accurate and high-frequency output. VCOs are voltage-controlled oscillators, which means their output frequency varies with an applied input voltage. They can be programmed to a wide range of frequencies, and it is this programmability that makes them ideal for many modern applications. The output frequency of the SIT8208AI-3F-18S-50 is digitally controlled by up to 6-bit control codes.

The SIT8208AI-3F-18S-50\'s high frequency output accuracy and low jitter performance make it an ideal frequency source for applications where cost and power efficiency are key considerations. It features an ultra-low phase noise, with a minimum RMS phase jitter of 0.8ps, and low start-up current that enables long battery life. Its frequency stability is better than ±20 ppm over the extended temperature range of -20°C to 70°C, with an additional stability of ±50 ppm over a temperature range of -40°C to 85°C. Furthermore, it offers exceptional long term stability, with drift rates of 0.3 ppm/year.

The SIT8208AI-3F-18S-50 is the perfect choice for electro-phonic designs with multiple frequency requirements and stringent frequency accuracy requirements. Its ultra-low power consumption, programmable range, reliable accuracy, and wide temperature range make it ideal for applications where stability over temperature, jitter performance, and cost-effectiveness are needed.
