Programmable Timers and Oscillators: 8N4DV85LC-0124CDI Application Field and Working Principle

Programmable timers and oscillators are essential components of many electronic devices, used to regulate a variety of electrical operations such as repetitive tasks, communication signals, and frequency synthesizers. 8N4DV85LC-0124CDI oscillators and timers are small, general purpose devices used to measure time. The basics of the 8N4DV85LC-0124CDI application field and working principle will be discussed below.

Application

In general, the 8N4DV85LC-0124CDI oscillator/timer is used in devices that need to produce a signal at regular intervals. It is most often used in applications such as motor speed control, signal regulation, and pulse generation. It is also frequently used in communication networks to maintain synchronization between nodes.

The 8N4DV85LC-0124CDI oscillator/timer is typically used in telecommunications applications to measure delay times for packets traveling through a system, thereby enabling accurate speed and data rate control. It is also used in mobile radio network control applications. In addition, the device may be utilized in combination with other timekeeping components, such as quartz crystals and phase-locked loops, to ensure accurate timing across a wide temperature range.

Working Principle

The 8N4DV85LC-0124CDI oscillator/timer is a low-cost programmable solution that contains a 12-bit timer/counter, clock oscillator, watchdog timer, and interrupt controller. The 8N4DV85LC-0124CDI is capable of producing signals at regular intervals and is used to measure the on and off times of pulse-width modulation (PWM) signals and other digital signals. The device is programmable, allowing users to adjust the width of the output pulses.

The 8N4DV85LC-0124CDI oscillator/timer operates by generating a square-wave signal at a specified frequency determined by its programmable registers. The device contains a 16-bit programmable prescaler and a counter that can be set to produce an interrupt or pass a condition after a specific time. When the timer is set with a given frequency, the counter is used to count down to zero. A timer compare register is also used to specify the time between interrupts, allowing for precise and accurate frequency control.

The 8N4DV85LC-0124CDI is capable of generating a pulse width modulation (PWM) signal, in which pulses of varying widths can be produced at fixed frequencies. To achieve this, the clock oscillator is first programmed with a desired frequency and then the timer counter is set to count up to a certain value. Once the timer counter reaches the specified value, the pulse width modulation (PWM) output line is set low until the counter reaches zero. This allows for the modification of the pulse widths at fixed intervals.

The 8N4DV85LC-0124CDI oscillator/timer also features a watchdog timer, which is used to ensure that the system does not enter an unexpected operating state. The watchdog timer monitors the device’s status and can generate an interrupt if it detects any unexpected behavior. This ensures that the system remains in a predictable state, which can improve reliability.

The 8N4DV85LC-0124CDI oscillator/timer is a versatile programmable solution for timing operations that require precise and accurate control. It is commonly used in a variety of applications and is an ideal choice for controlling frequency or creating pulse-width modulation (PWM) signals. The device is adaptable, and its registers can be programmed to suit the specific needs of a given system’s timing requirements.
