Programmable Oscillators: SIT1602BIR7-30S Application Field and Working Principle

Programmable oscillators are self-contained, integrated timing systems that are used to generate a wide range of clock and signal frequencies or waveforms. They make use of components such as crystal oscillators, TCXOs, VCXOs, and standard oscillatory circuits for their operation.

Programmable oscillators can be used to make various adjustments to the signal output, such as adjusting the output frequency, changing the duty cycle, entering digital codes to control the oscillator\'s parameters, and so on. They are widely used in applications such as computer, communication, digital signal processing, and military systems.

One of the most popular programmable oscillators is SIT1602BIR7-30S. It is a highly integrated and low-consumption, programmable oscillator device with built-in SLG59M7889MI-SP01 48MHz microcontroller, which supports a wide frequency range from 8MHz to 24MHz with accuracy of 20ppm. It also has 42 general chip I/O ports, 10 programmed I/O, up to 40 programmable parameters.

SIT1602BIR7-30S can be used to generate clock and signal frequencies ranging from 8MHz to 24 MHz. And its application field covers automotive electronics, industrial automation control, consumer electronics and space industry. It is also used in wireless Lan, radio frequency modem, TV/video and interactive multimedia systems.

The working principle of SIT1602BIR7-30S is focused on the use of an ultra-low power microcontroller to generate a highly accurate and stable clock or signal frequency. It relies on two main parts: the internal clock system and frequency calibration circuit. The internal clock system consists of several oscillatory modules comprising filters, frequency dividers and phase detectors, providing clock and signal frequencies across the whole range. The output frequency is then precisely calibrated by the use of the frequency calibration circuit. It corrects the output frequency by comparing the actual output to the stored nominal value. The calibration data is stored and can be accessed from the chip interface.

In conclusion, SIT1602BIR7-30S is a programmable oscillator that can be used in a wide range of applications, such as automotive electronics, industrial automation control, consumer electronics and space industry. It relies on an ultra-low power microcontroller to generate a highly accurate and stable clock or signal frequency, and uses a frequency calibration circuit to precisely calibrate the output frequency by comparing the actual output to the stored nominal value.
