Introduction to SIT8208AI-81-25S-31.250000Y

SIT8208AI-81-25S-31.250000Y is a type of oscillator manufactured by Epson Toyocom which is part of the subcategory called “Oscillators” or an electronic device designed to generate a periodic signal with a precisely defined frequency and amplitude. It is often used as a timing reference in electronic circuits, and is available with various frequency ranges, drive levels and packaging styles to suit the requirements of a wide variety of industries and applications. They were designed specifically to provide a stable and precise frequency output with low voltage requirements.

Features of SIT8208AI-81-25S-31.250000Y

SIT8208AI-81-25S-31.250000Y’s primary feature is its low power consumption. It uses less than 0.1µA when in its stop mode and it requires only 4.4v at an operating frequency so that the power output can be kept to its lowest minimum. Additionally, this oscillator has very low jitter (<1ps) and phase noise which helps in producing a very robust output signal. It also has an impedance of 50 ohms making it well-suited to be used with some of today’s digital and analogue loads.

Application and Working Principle of SIT8208AI-81-25S-31.250000Y

This type of oscillator is most commonly used in time keeping applications such as digital clocks. They provide an accurate and stable reference frequency that can be used by a microcontroller or other digital circuitry operating within a need of controlled timing. The device works by using an RC network (Resistor-Capacitor network) with an adjustable resistor and a pair of capacitors connected in parallel. When a square wave input is applied to either of the terminals, the capacitors will charge and discharge at different rates due to the different resistance values. This causes the time difference between the high and low points of the waveform to change, resulting in an output frequency dependent on the resistor value.The SIT8208AI-81-25S-31.250000Y oscillator can also be used in a variety of other applications such as a pulse-width modulator, digital filter and signal source in telecommunications systems. It can also be used as a timekeeper in modems, data acquisition systems, radio controlled clocks, motor/heater controllers, servo/stepper controllers, and other circuits requiring precise and stable timing.

Conclusion

The SIT8208AI-81-25S-31.250000Y oscillator from Epson Toyocom is an excellent device for applications that require precise and stable frequency outputs. Its low power requirements, low jitter, and low phase noise make it ideal for use in digital and analog designs. It can be used for a variety of other applications such as timekeeping, pulse-width modulator, digital filter and telecommunications. It is important to remember, however, that while the oscillator can provide a constant frequency output, it is not guaranteed to be perfectly stable over extended periods of time.
