Working Principle

The 8N4DV85BC-0176CDI8 is a programmable frequency synthesizer that uses a clock generator, timer/counter, and multiple programmable settings to produce a wide range of output signals. An external clock signal is used to trigger the input of the timer/counter and set the frequency output. In order to program the timer/counter, the user must set the following parameters: the frequency of the output signal, the type of output signal, the period of the signal, and any desired additional settings such as edge-triggered or level-triggered pulse settings.The 8N4DV85BC-0176CDI8 then produces the desired output signal based on a combination of these settings. The output signal is produced when the timer/counter reaches a preset count and is then reset to the original count. This process is repeated every time the timer/counter reaches the preset count. The frequency output from the device is then determined by the frequency of the external clock signal combined with the settings programmed into the timer/counter.

Conclusion

The 8N4DV85BC-0176CDI8 is a highly programmable, low-cost, low-power device designed for a wide range of timing and oscillator applications. It offers a variety of features and benefits, including a large selection of operating modes, programmable settings, and external clock and reset capabilities. It is capable of producing a wide range of output signals depending on the programmed settings and external clock signal.
