Programmable Timers and Oscillators are essential components on modern circuitry, providing synchronisation between multiple systems and modules, while at the same time enabling engineers and designers to create reliable, high-performance products with precision timing. The 8N3SV76BC-0129CDI8 is an example of a programmable timer and oscillator, suitable for many applications. This guide will cover both the application field and working principle of this device.

Application Field

The 8N3SV76BC-0129CDI8 is a Gigahertz-band programmable timer, offering high accuracy and stability. Its main applications are in automotive, consumer electronics and industrial applications. Automotive applications include engine control, AUTOSAR synchronization and powertrain management systems. In consumer electronics, the timer is useful for cellular and Wi-Fi systems and camera systems, while in industrial applications, it can be found in industrial automation, instrumentation and building automation.

The 8N3SV76BC-0129CDI8 offers low power consumption, robustness and reliability. The device is rated for wide temperature operations, from -40 to 85 °C, and can withstand temperature shocks up to 200 °C. It has support for multiple programming configurations, and offers automatic adjustment of the internal timekeeping system. In addition, the device features an integrated frequency discriminator, allowing users to detect and adjust frequency discrepancies with ease.

The 8N3SV76BC-0129CDI8 is able to synchronise with a wide range of external systems, such as GPS, Ethernet, USB, PLC and RS485. This makes it an ideal choice for synchronising systems across distributed architectures and complex network structures. It is also capable of synchronising with legacy systems, making it an ideal solution for updating older systems where synchronisation technology has been outdated.

Working principle

The 8N3SV76BC-0129CDI8 utilises a low-noise, high-accuracy, crystal-controlled timing circuit, designed for reliable clock and frequency synchronisation. The oscillator is based around a quartz crystal resonator, which is used to generate a defined frequency of oscillation. This frequency is then used as a reference signal to the internal timekeeping circuit. The oscillator also features a frequency discriminator, which allows users to detect and adjust frequency discrepancies.

The timer is programmed using a simple, serial communication interface, which allows for easy configuration of the device. This interface also provides the ability to read out the current frequency and other information, such as the current temperature, as well as to adjust the internal timekeeping system. The 8N3SV76BC-0129CDI8 also supports two programmable trigger outputs, allowing users to set specific frequency or time thresholds or events.

In addition to the internal timekeeping circuit, the 8N3SV76BC-0129CDI8 also features dedicated clock outputs. These outputs can be used to synchronise external systems, or to drive auxiliary circuitry, such as LED displays and graphical LCDs. The output frequency can be adjusted from a few Hz to GHz range, allowing for great flexibility in system designs.

Conclusion

The 8N3SV76BC-0129CDI8 is a programmable timer and oscillator offering a great set of features for both automotive, consumer electronics and industrial applications. It offers great stability and accuracy, as well as temperature rating up to 200 °C and low power consumption. The device features an intuitive programming interface and supports multiple external synchronisation protocols. The integrated frequency discriminator and clock outputs further extend the versatility of the timer, making it an ideal choice for many applications.
