Oscillators

Oscillators are used in many electronic circuits to create frequencies and generate signals. In this article, we will discuss the application field and working principle of the SIT8208AC-G2-25E-12.288000X oscillator.

Application Field

The SIT8208AC-G2-25E-12.288000X is a low cost miniature ultra-low frequency oscillator. It is often used in applications such as medical systems, automotive, process control, consumer electronics, and wireless communications systems. It is available in a variety of packages such as SOT23 and the SC-70 packages.

The SIT8208AC-G2-25E-12.288000X is designed for supply voltages from 2.8V to 3.6V. It is also suitable for use in high-temperature applications. It can operate over a wide temperature range, ranging from -40°C to 105°C. It also has a low power consumption of only 250 µA.

Working Principle

The SIT8208AC-G2-25E-12.288000X oscillator works on the principle of a PLL (Phase Locked Loop). A PLL is a closed loop system which consists of a Voltage Controlled Oscillator (VCO) and a phase comparator. The purpose of the PLL is to compare an input signal with an output signal and adjust the output signal until they match. This is done by using an Integrator, which compares the two signals and gives an output to the VCO. The VCO then adjusts its frequency until the two signals match.

The SIT8208AC-G2-25E-12.288000X oscillator also has a VCDL (Variable Capacitor Diode Logic) circuit which further increases the frequency accuracy. The VCDL circuit consists of a number of capacitors and diodes, which are connected in a series configuration. When the oscillator is running, the capacitors are connected in parallel, thus reducing the total capacitance and increasing the frequency accuracy.

In addition to being used in a PLL configuration, the SIT8208AC-G2-25E-12.288000X oscillator can also be used in a standard free-running configuration. In this configuration, the oscillator works without any feedback from an external source and is typically used for applications that require low power consumption.

Conclusion

The SIT8208AC-G2-25E-12.288000X oscillator is a versatile and reliable low cost miniature ultra-low frequency oscillator. It is well suited for use in a wide range of applications such as medical systems, automotive, process control, consumer electronics, and wireless communication systems. In addition to being used in a PLL configuration, it can also be used in a standard free-running configuration. It is designed to have a low power consumption and operate over a wide temperature range.
