Programmable Timers and Oscillators

The 8N4Q001KG-1149CDI8 is a programmable timer and oscillator that suits a wide variety of applications. By adjusting the values of two capacitors, this chip can be used to accurately generate and measure a wide range of frequencies and timing intervals. It features an auto-calibration feature that makes it easier to set up and use than other comparable devices.

Application Field

The 8N4Q001KG-1149CDI8 is mainly used in power supplies, STBs (Set Top Boxes) and communications systems. It is widely used in the design of electronic equipment such as power conditioners, air conditioners, small motors, monitors, and digital cameras. It is also used in the backlighting and color control of LCDs, and digital oscilloscopes.

Working Principle

The 8N4Q001KG-1149CDI8 works by monitoring the periodic frequency oscillations that emerge when two capacitors are operatively coupled. Then, it reacts by emulating a reference frequency based on the measured oscillations. This reference frequency is fed to a timer that patterns the values of two capacitors until this reference frequency is exactly matched. The matched frequency is ensured when the timer is finally reset.

This programmable timer and oscillator is also equipped with an auto-calibration feature. When activated, the operator does not have to manually adjust the values of the external capacitors. Instead, the chip automatically identifies the reference frequency and matches the capacitors accordingly. This substantially reduces the amount of time and effort needed to set up the 8N4Q001KG-1149CDI8.

In essence, the 8N4Q001KG-1149CDI8 is an efficient, highly accurate programmable timer and oscillator. It is an ideal fit in power supplies and electronic equipment that require this level of control and accuracy.
