Working Principle

The 8N3DV85AC-0004CDI programmable timer and oscillator uses voltage controlled oscillator (VCO) technology to control frequency, duty cycle and pulse duration. The working principle of the 8N3DV85AC-0004CDI is that the parameter being adjusted is connected to the VCO which in turn is connected to an internal counter and output register. When the user changes a parameter, the changes are first written to the output register and then acted upon by the internal counter.

For example, if a user wants to increase the pulse duration, this will be done by increasing the value of the internal counter. This increase in counter value causes an increase in the output frequency, and consequently, the pulse duration increases. The same principle applies when decreasing the pulse duration. The counter value is reduced and the output frequency is reduced indicating a decrease in the pulse duration.

The 8N3DV85AC-0004CDI timer also has ability to offer user feedback. This can be done by connecting the output of the timer to a feedback loop which monitors a specific condition and then actuates the counter to provide the desired pulse duration. This feature is useful for applications where accuracy and timing is critical.
