8N4Q001FG-1018CDI8

8N4Q001FG-1018CDI8 is a programmable timer and oscillator device that combines an 8-nP Divide-by-N prescaler with a 10-bit down counter and dual 8-bit Output Stop Counter. It provides a low power, high accuracy timing solution for applications such as embedded clocks, automotive display timing or scheduling tasks in communications systems.

Application Field

The 8N4Q001FG-1018CDI8 is used for Clock/Timing generic applications such as motor control. This device can be used in many industrial applications such as programmabling a signal’s duty cycle, counter applications, and timer applications. It can schedulle tasks in communications systems, and automotive display timing. It also can generate precise timing signals and frequencies in embedded clocks and communications system to ensure correct synchronization and transmission of data. It can be used in consumer applications such as digital watches and clocks. It can also be used in low power applications when the the Analog Digital Converter (ADC) requires a quantity of time before capturing subsequent data.

Working Principle

The 8N4Q001FG-1018CDI8 working principle is based on the combination of two main components: the 8-nP divide-by-N prescaler and the 10-Bit down counter/dual 8-Bit Output Stop counter. The 8-nP prescaler uses pulse-width modulation (PWM) for clock signal generation where the prescaler divides down input clock reference frequencies by powers of 2 and 8. The 10-Bit down counter functions by counting down from some initial value, typically all ones. When the counter hits zero, it is reset to the initial value and start counting down again. In addition, the device is equipped with dual 8-bit Output Stop Counter that can be used in initial system startup when fast rise time on the output is not necessary. This allows the user to program the frequency output to start at any frequency above the most sensitive frequency range of the device.

It also provided with the extended power down feature that saves the current charge and counter values during power down mode, which would enable the device to resume the countdown from the last counted state. The device also features a period register and variable duty cycle that can be programmed for precision frequency/duty cycle control.

In summary, the 8N4Q001FG-1018CDI8 is a programmable timer and oscillator that provide precise frequency, duty cycle, and timing control for industrial and consumer applications.
