Programmable timers and oscillators are devices used to accurately measure intervals of time. The 8N3QV01KG-0158CDI8 is a programmable timer/oscillator chip in the field of clock/timing solutions. This article covers the 8N3QV01KG-0158CDI8’s application field and working principle.

Overview

The 8N3QV01KG-0158CDI8 is an 8-bit programmable timer/oscillator integrated circuit, featuring clock output divider and differentiating, or regenerative control of output signals. This chip can produce accurate timing solutions in the range of 1 Hz to 10 MHz and is suitable for use in precision timing provisions, such as in clocks, audio/video synchronizers, datalink interfaces, personal computers, microcontrollers, and embedded processor systems. The 8N3QV01KG-0158CDI8 produces a 50% duty cycle on its output during operation, and can be combined with a logic gate to produce non-50% duty cycles. The chip also has the ability to output logic low or high levels, depending on the settings. The 8N3QV01KG-0158CDI8 chip is packaged in a 24-pin DIP. It requires a single +5V voltage supply and consumes very low power, making it suitable for battery-powered devices.

Working Principle

The 8N3QV01KG-0158CDI8 timer/oscillator uses a counter to divide the input clock frequency and thus provide accurate timing. The chip consists of a programmable frequency divider, a latch, and a logic generator circuit. The programmable frequency divider generates an output frequency that is a fraction of the input frequency. For example, if the input frequency is set to 5 MHz and the frequency output is set to 1 kHz, the frequency divider will divide the input frequency by 5000. This output is sent to the latch, which acts as a memory and stores the output rate so that it can remain constant even when the input frequency changes. The logic generator circuit is responsible for producing a logic low or high output depending on the settings. For example, when the logic low output is selected, the logic generator will output a logic low signal when the counter has counted up to a certain number. Similarly, when the logic high output is selected, the logic generator will output a logic high signal when the counter has counted up to a certain number.

Conclusion

The 8N3QV01KG-0158CDI8 is an 8-bit programmable timer/oscillator integrated circuit that is suitable for use in precision timing provisions. It produces a 50% duty cycle on its output during operation and can be combined with a logic gate to produce non-50% duty cycles. The 8N3QV01KG-0158CDI8 uses a counter to divide the input clock frequency and thus provide accurate timing. It requires a single +5V voltage supply and consumes very low power, making it suitable for battery-powered devices.
