The 8N3SV76BC-0181CDI8 is a component of the Clock/Timing family of Programmable Timers and Oscillators. This device is a programmable timer/oscillator circuit, which has a wide range of application fields and a unique working principle.

Application Fields

The 8N3SV76BC-0181CDI8 is built for versatile functions, making it suitable for many application fields. It is utilized for the most general purpose timer and clock generator circuits. It can be used for a variety of functions, such as CPU/core frequency synthesizing and synchronization. In addition, it can be utilized for real-time control applications, such as sensor data acquisition and thermal sensing.

It is also useful for communication systems, cellular base stations and power management systems. For example, it is capable of switching power supply configurations for lower power consumption. Furthermore, it can be employed for short-term, low-power system timing where the device is not active or powered continuously.

Working Principle

The 8N3SV76BC-0181CDI8 timer/oscillator circuit is controlled by a 4-wire bus interface that supports both I2C and SPI. It provides adjustable frequency operation with a 19.2MHz maximum frequency. This device utilizes inductor and capacitor components as the frequency tuning components.

The oscillator consists of a control circuit including control logic, memory, digital-to-analog converter, phase-frequency detector, voltage-controlled oscillator, and clock divider. The phase-frequency detector produces a phase error signal from the difference between the inputs and the output of the VCO, and the frequency error is then generated with the phase error signal and reference frequency. The output clock is continuously adjusted in order to match the set clock frequency.

The 8N3SV76BC-0181CDI8 is capable of accepting an auxiliary clock which is used to synchronize the oscillator. This enables an external synchronization clock to control the frequency of the device from an external source. This device also features programmable PDAs (Phase-Domain Auto-tuning) and HDAs (Hysteresis Domain-Auto-tuning) functions, which dynamically adjust the frequency when the PDAs or HDAs are enabled.

The 8N3SV76BC-0181CDI8 also offers an immune linear regulator function that provides output voltage with a higher immunity to external noise. This device is also designed to make it more difficult for the internal circuit components to become unstable due to sudden surges or changes of the input power.

Conclusion

The 8N3SV76BC-0181CDI8 is a programmable timer/oscillator circuit that is highly reliable and versatile. Its robust design allows it to fit into a variety of application fields, such as communication systems and power management systems. In addition, its unique working principle enables it to provide adjustable frequency operation and various functions through its 4-wire bus interface. This makes the 8N3SV76BC-0181CDI8 a great choice when it comes to Programmable Timers and Oscillators.
