Programmable timers and oscillators are commonly used devices that perform functions like generating signals at precise intervals, creating a clock for digital circuits, and controlling motion in relays and motors. The 8N3DV85KC-0086CDI is one such programmable timer and oscillator device. This article will discuss the application field and working principle of the 8N3DV85KC-0086CDI.

The 8N3DV85KC-0086CDI is a versatile device that can be used in a wide range of applications, such as real-time clock and timer systems, frequency synthesis, and pulsed signal generation. For example, in real-time clock and timer systems, the 8N3DV85KC-0086CDI can be used to generate a signal at a precise interval, allowing the system to accurately track time. This is achieved by programming the timer to generate a signal at a pre-defined interval. Similarly, in frequency synthesis, the device can be used to generate signals of a fixed frequency. This is done by programming the timer to generate a signal at a specific frequency, generating a stable signal with minimal discrepancies. Similarly, in pulsed signal generation, the device can be used to produce signals with a specific pulse duration and time interval. This Pulse Width Modulation (PWM) signal can be used to control the speed of a motor or a relay.

The 8N3DV85KC-0086CDI is an integrated circuit which comprises of an oscillator and timer circuit, which are connected in series to form a single device. In the first stage, the oscillator receives an external frequency reference signal, typically from a quartz crystal. The oscillator then amplifies the reference signal and sends out a replica at a multiple of the reference frequency. This replica frequency is then passed to the timer circuit, which is used to generate the required signals.

The timer circuit divides the replica frequency into smaller sub-frequencies which can be programmed as per the application requirement. The division of the frequency is achieved by a process known as pulse-width modulation. In this process, the timer circuit varies the time duration of each pulse, such that the average frequency is reduced. This division of the replicated frequency allows timing of specific intervals, which can be used to generate signals at a desired interval.

The 8N3DV85KC-0086CDI also comprises of an output driver circuit, which is used to convert the digital signals to an appropriate voltage level that is suitable for the application. The output signal can be further configured by setting the pulse width (duration of digital pulse) and time interval (time between two consecutive pulses). The output voltage and frequency of the signal can also be adjusted, as per the requirements of the application.

In summary, the 8N3DV85KC-0086CDI is an integrated, programmable timer and oscillator device, which can be used in applications such as real-time clock and timer systems, frequency synthesis, and pulsed signal generation. It is composed of an oscillator and timer circuit, which are connected in series. The device receives an external frequency reference signal, which is amplified by the oscillator circuit and further divided by the timer circuit. Finally, the output is produced by the output driver circuit, which can be configured as per the requirements of the application.
