This article will explore the application fields and working principles of the ICM7242IBAZ Programmable Timers and Oscillators.

Application Fields

The ICM7242IBAZ can be used for a wide variety of digital applications, ranging from very low power and low cost designs to high performance systems. The ICM7242IBAZ can be used for system synchronous functions, such as clocks and timers. It can also be used as a clock or timer in a wide variety of digital signal processing applications and high speed designs, such as data capture, data streaming, digital signal processing, and digital filtering. The ICM7242IBAZ is ideal for use with digital logic families such as bipolar logic, TTL, and CMOS.

Working Principle

The ICM7242IBAZ features a programmable array of 12 timer/oscillator devices, each of which contains a digital counter, timer, clock, and pulse output generator. The application of these various devices can be configured to generate a variety of waveforms, including sine, triangle, sawtooth, and rectangular waveforms. The ICM7242IBAZ also contains two additional input and output pins for external control of the pulse toggling and counter reset functions.

The ICM7242IBAZ can be programmed to generate both single-cycle and multi-cycle waveforms, by adjusting its timer/oscillator array. For single-cycle waveforms, the delay time can be adjusted, to select the desired waveform frequency. For multi-cycle waveforms, the array can be programmed to generate a pulse, and then be reset by an external signal. The counter can also be stopped and restarted by an external signal, to create an adjustable duty cycle or pulse rate.

The ICM7242IBAZ features an adjustable digital frequency divider, with a selectable division factor of up to 255. It also contains a programmable pulse width modulation circuit, allowing for a wide range of pulse widths to be generated. The device additionally contains an asynchronous reset circuit, allowing for an adjustment in the phase of the signal output.

Finally, the ICM7242IBAZ also contains an edge triggering circuit, which allows for triggering from either rising or falling edges of the input signal. This allows for higher precision when it comes to tasks such as video synchronization and timing applications.

Conclusion

The ICM7242IBAZ is a versatile programmable integrated circuit, capable of performing a variety of timing and clock management functions. It is an ideal choice for use in a wide range of applications, ranging from low power and low cost designs to high performance systems. With its programmable array of 12 timer/oscillator devices, adjustable digital frequency divider, programmable pulse width modulation, and edge detection capabilities, the ICM7242IBAZ allows users to generate the precise waveforms that their applications require.
