Programmable Oscillators: SIT1602BCL3-25S Application Field and Working Principle

Programmable oscillators are a type of custom oscillator that is easily adjustable and customized by the user for their desired clock frequency, often for the purpose of micro-processing, embedded computing, and digital audio. A programmable oscillator uses a small built-supplied component such as quartz crystal with a large number of electrodes to provide the electrical contact needed for programming. The programmable oscillator can be used for signal manipulation, for example for clock scale accuracy improvements, signal conditioning applications, and other signal requirements. The SIT1602BCL3-25S is a programmable oscillator.

SIT1602BCL3-25s Application

The SIT1602BCL3-25s is a low-power linear-frequency programmable oscillator that achieves an AC power factor of 0.1 to 0.5 and a maximum output frequency of 2 GHz. This type of oscillator can be used in various applications that require a stable signal, such as clocks, synthesizers, and counters. Clock accuracy and frequency stability are critical in synchronizing system components during information transfer, protecting data integrity, and in controlling high-speed digital signal processing devices.

SIT1602BCL3-25s Working Principle

The SIT1602BCL3-25s programmable oscillator works by allowing the user to configure a signal inputrange from 0 Hz to 2 GHz. The oscillator itself is a digitally controlled clock signal generator, enabled by a programmable oscillator control IC. The oscillator consists of an input amplifier, a phase frequency detector, a low-pass filter, an adjustable voltage-controlled crystal oscillator, a reference oscillator, and a calibrated clock output stage. The oscillator input signal is amplified by the input amplifier and then sent to the phase frequency detector. The phase frequency detector is responsible for comparing the input signal frequency and phase to the reference clock signal. The result of this comparison is passed through the low pass filter, resulting in an adjustable voltage-controlled crystal oscillator output. This adjustable VCO output is the calibrated clock signal that is then used to drive the output stage of the oscillator.

Conclusion

The SIT1602BCL3-25s is a programmable oscillator that offers a high frequency and accuracy for a wide range of applications. It is a digital clock signal generator that can be programmed for a wide range of signal inputs, resulting in an accurate and stable output signal. It utilizes an amplifier, a phase frequency detector, a low pass filter, and an adjustable voltage-controlled crystal oscillator in order to produce the desired output. With its low-power consumption, high-frequency and accuracy, it is a valuable addition to any system requiring precise timing control.
