Programmable Timers and Oscillators

8N4SV76FC-0008CDI is a type of programmable timer and oscillators. It continuously and accurately measures elapsed time anywhere from milliseconds to hours in a variety of applications. These timers employ a signal from a quartz crystal oscillator or resonator, which is used to measure the passage of time.

Application Field

8N4SV76FC-0008CDIprogrammable timers and oscillators are widely used in digital systems, embedded systems, industrial controllers and other automated equipment that require precise time measurement. Examples of applications include switch reset timing, one-shot time delimiting, clock synchronization, frequency measurement and gating control functions.

Working Principle

8N4SV76FC-0008CDI programmable timers and oscillators use a quartz crystal as the timing element. It consists of the frequency setting circuit and a set of programmable counter/timer circuits for counting clock pulses. As the clock oscillator circuit provides the required frequency signal, the signal runs through a frequency selection circuit where the frequency is then conditioned for signal processing and routing.

The signal is then routed to the counter/timer circuits which can perform various timing and functions such as interval timing or pulse counting, depending on the user program. The signal is then routed to the output terminals, where it can be used to trigger the appropriate circuitry.
