Introduction

The 8N4DV85AC-0069CDI8 Programmable Timers and Oscillators are designed to provide an accurate timing signal in a wide range of applications. The timer and oscillator combination is designed to reduce power consumption and simplify the design process. This can be achieved by programming the frequency, period, current settings, or by selecting the exact timing configuration for the application.

Application Field

The 8N4DV85AC-0069CDI8 Programmable Timers and Oscillators is used in industrial electronic systems, such as clock and timer signal generation. By using this programmable timer, the exact amount of time can be easily programmed to optimize the performance of electronic system that needs accuracy in timing. Because of its low power consumption, the 8N4DV85AC-0069CDI8 is also suitable for portable applications, such as mobile phones and personal digital assistants (PDAs).Other popular application fields include automatic vehicle control systems, medical devices, remote controls, home security systems, aerospace, microprocessor based systems, numerical control systems and robotics.

Working Principle

The 8N4DV85AC-0069CDI8 Programmable Timers and Oscillators works in a two-stage process. The first stage of the process is a configuration stage that allows for setting the frequency, period, and current settings. The second stage is the start-up sequence and will initiate the clock output from the integrated oscillator.The timer has two frequencies - slow and fast. The slow frequency is used to optimize the performance of the electronic system while the fast frequency is used to increase the time resolution. The clock output can be set to operate in various modes, such as single, dual, or dual-delay. The 8N4DV85AC-0069CDI8 also includes a built-in over-voltage protection circuit to prevent electrical damage to the device due to high voltages. The timer is also capable of synchronized start and stop pulse control to ensure reliable operation.The internal timer is an electronic programmable time base providing accurate timing signals. The time base consists of a programmable counter, an accumulator, and non-volatile memory. The accuracy and speed of the timing signals can be improved by using a temperature compensated crystal oscillator (TCXO). The TCXO is a type of crystal oscillator that is optimized for frequency and temperature stability. The frequency accuracy of this oscillator is higher than that of digital timers.

Conclusion

The 8N4DV85AC-0069CDI8 Programmable Timers and Oscillators is an ideal solution for a variety of applications in various types of industrial electronic systems. This timer and oscillator combination is designed to reduce power consumption and simplify the design process. The timer has two frequencies - slow and fast - which allows for customizing the performance of the system and for increasing the time resolution. Furthermore, the timer is equipped with a number of protection circuits and is capable of synchronized start and stop pulse control. With its low power consumption, the 8N4DV85AC-0069CDI8 is suitable for portable applications, such as mobile phones and personal digital assistants (PDAs).
