Clock/Timing - Programmable Timers and Oscillators

The 8N4SV76AC-0038CDI8 Timers and Oscillators is a programmable clock generator. It is designed to generate an arbitrarily programmable clock pulse signal of different frequencies and shapes. The programmable timer and oscillator give engineers the freedom to generate multiple signals sequentially or simultaneously, providing complex, high-performance timing and clock signal generation for high speed embedded designs.

Application Field

This programmable timer and oscillator family is designed for embedded applications that need precise and reliable operation with customizable frequencies and operating parameters. Applications include military communication systems, HDTV broadcast and high-end data/network cards. Additionally, the 8N4SV76AC-0038CDI8 is well suited for various automation, control, digital audio and video and test and measurement equipment.

Working Principle

The 8N4SV76AC-0038CDI8 programmable timers and oscillators use a programmed lookup table (LT) to generate clock pulse signals. The LT is programmed by writing specific values to the 16-bit General Purpose Programmable Register (GPR). When a frequency is changed, the values are written again to the GPR, which produces different clock pulse signals. The user is given full flexibility in configuring the clock parameters, such as the duty cycle, output type (push-pull or open-drain) and transition time states. By utilizing the programmable LT, any arbitrary waveform or frequency can be programmed.

Conclusion

The 8N4SV76AC-0038CDI8 programmable timers and oscillators are specifically designed for complex and high-performance timing and clock signal generation. It has substantial advantages over other timer or oscillator solutions, as its frequency and waveform parameters are completely configurable, allowing engineers the freedom to produce ideal timing signals for their specific applications.
