Clock/Timing—Application Specific is a specialized section dedicated to the implementation, application, and use of application specific timing signals. The 97ULP845AH is a clock/timing application specific device which is designed to produce timing pulses, or clock signals, according to a specific frequency. Here, we will discuss the application field of the 97ULP845AH, as well as the working principle behind it.

Application Field

The 97ULP845AH is an effective precision timing device with a microprocessor-controlled regenerative element which is well-suited for triggering ultra-low power microcontrollers, Actel field programmable gate arrays (FPGA), and similar digital logic devices. Its low power consumption and controlled timing signals make it ideal for low-frequency applications such as power clock distributions and universal serial bus (USB) applications.

Since it features a dedicated output driver, the 97ULP845AH is also suited for system synchronization in which the clock enables applications to stay smoothly functioning. This is especially useful in applications such as medical imaging which need to stay continuously running and remain in synchronization with the rest of the system. Furthermore, the 97ULP845AH can also be used in PLC applications where it helps keep clocks in sync as well as providing timing pulses for various intermittent operations.

Working Principle

Essentially, the 97ULP845AH acts as a timing device that sends electrical pulses to its output pin after a certain set period. It works by utilizing its internal oscillator, a circuit which behaves like a saw-tooth wave, to output a clock signal after a certain period. This clock signal is then sent to a regenerative element, a component which pauses the process for a set time before allowing a new oscillation cycle to start, thus creating a delay for the output pulse.

The pulse interval can be adjusted by adjusting the variable the frequency setting, thus allowing the user to determine the desired frequency of the clock. Furthermore, since the 97ULP845AH is also programmed by means of an external microprocessor, it can provide highly accurate pulse intervals as well as changing pulse rates as the user desires.

In addition, the 97ULP845AH is equipped with a flexible wake-up feature which enables users to wake up the device from a deep sleep with a minimum current consumption. This feature is especially useful for applications with intermittent needs since the device can go into sleep mode and still run efficiently when it is required.

Conclusion

In conclusion, the 97ULP845AH is a precision timing device which is designed to provide accurate and reliable clock signals for applications that need precision timing. With its low power consumption and adjustable frequency settings, it is ideal for low-frequency applications such as power clock distributions and medical imaging. Furthermore, the 97ULP845AH is also equipped with a wake-up feature which enables it to wake up from a deep sleep with a minimum current consumption, making it suitable for applications with intermittent needs.
