9FG831AGLF Application Field and Working Principle

The 9FG831AGLF series is categorized as a Clock/Timing - Application Specific IC. It is a chip that contains completely integrated timing devices suitable for commercial and industrial applications.

Manufactured by Advanced Semiconductor, Inc., the programmable 9FG831AGLF provides frequency generating, interval measuring, and watch-dog timer functions. It also offers a variety of frequency and counter functions suitable for control purposes.

Application Field

The 9FG831AGLF series is suitable for a wide range of applications. Its features provide possibilities in the electronics industry, energy industry, telecoms industry, and the automotive industry, amongst others.

Within the electronic industry, it is widely used for frequency synthesis of synthesizers and modulators in communication systems and radar. In the energy industry, it is used for power supply regulation, control, and measuring purposes. In the telecom industry, it is used for a multitude of signaling applications, such as frequency synthesis for modems and frequency-shift exchanged for synchronous modems. And in the automotive industry, the 9FG831AGLF series is used for frequency synthesis in resolvers, electronic fuel injection, and ABS systems.

Working Principle

The 9FG831AGLF features a programmable counter, two independent frequency/time compare outputs, two pulse out outputs, and two logic output signals. The logic outputs are generated when the divided counter values match the programmable reference values.

The two frequency counters can be used in three modes. In the compare mode, one counter is used to measure the input frequency, the other to compare it to a reference count. The two counters can also be used in the dual frequency counter mode, where two input frequencies are measured simultaneously. In the dual-time mode, two time periods are counted.

The pulse output function operates in a range from 0-1.2MHz, and it is used to generate a pulse with a fixed width for each cycle of the input signal. The watch-dog timer mode is used for applications requiring an interrupt operation. It resets itself after a predetermined amount of time.

Conclusion

In conclusion, the 9FG831AGLF is an application specific IC that offers a variety of frequency and counter functions suitable for control purposes. It has a wide range of applications in various industries and it can be used to generate frequencies, measure intervals and provide watch-dog timer functions.
