The 8N3DV85LC-0177CDI8 is a clock/timing Programmable Timers and Oscillators designed for critical timing applications in embedded systems. It combines improved accuracy, precision, and repeatability with ease of use and a wide range of features for board-level timing functions. The 8N3DV85LC-0177CDI8 is available in three different packages, each containing a different performance level.

Applications

The 8N3DV85LC-0177CDI8 can be used in a wide range of applications requiring accurate timing including:

• Time/date setting and board-level synchronisation
• Time and frequency measurements
• Time and frequency generation
• Microcontroller-based control systems
• Audio/video synchronisation
• Communications systems
• Edge detection

Working Principle

The 8N3DV85LC-0177CDI8 uses a programmable counter/timer with crystal oscillator as a clock source to ensure highly reliable operation. The timer is designed to count the number of clock cycles between predetermined events and can be configured to shut off or reset after a certain number of counts. When enabled, the 8N3DV85LC-0177CDI8 generates a pulse on its output pin at intervals determined by the programmed time interval. This pulse can be used to trigger other circuits in the system or to reset other counters.

Operation

The 8N3DV85LC-0177CDI8 is programmed by configuring its registers according to the desired time interval. The time interval is specified as a preset value in seconds, minutes, or hours. The counter counts down at the rate of the crystal oscillator, and when the preset value is reached, a pulse is generated on the output pin. The timer can then be reset and start counting down again from the preset value. The 8N3DV85LC-0177CDI8 has the additional ability to control a second counter, allowing for longer time intervals.

In addition to its basic timing capabilities, the 8N3DV85LC-0177CDI8 supports two additional modes of operation; ‘Timer-to-Trigger’ and ‘Pulse-width-to-Trigger’. In these modes, the frequency of the pulse is increased and decreased respectively with respect to the preset value, allowing the user to have more control over their applications.

Advantages

The 8N3DV85LC-0177CDI8 provides a number of advantages over other timer/oscillators available in the market. These include:

• High accuracy and precision
• High repeatability
• Low power consumption
• High frequency accuracy and ultra-low jitter
• Compatibility with a wide range of applications
• Easy to configure and implement
• High immunity to external noise sources

Conclusion

The 8N3DV85LC-0177CDI8 is an excellent choice for time-sensitive applications. It combines high accuracy, precision and repeatability with low power consumption and an easy to configure and implement interface. In addition, the 8N3DV85LC-0177CDI8 offers a range of features for board-level timing functions, making it an ideal choice for complex timing applications.
