Evaluation and Demonstration Boards and Kits

An evaluation and demonstration board, or a product kit, is a type of electronic circuit board that mimics the functionality of a real, working product in miniature form so that each board can be tested and demonstrated in a laboratory or industrial environment before any commercial production. One example of such a product is ISL54400EVAL1Z, a component from Intersil corporation that provides a comprehensive and cost-effective solution for evaluation of the ISL54400 clock synthesizer device family. It serves as a versatile platform for evaluating the features, such as low-jitter output clocks and multiple clock outputs, and performance of the ISL54400/ISL54410 device family.

ISL54400EVAL1Z Application Field and Working Principle

Application Field

ISL54400EVAL1Z is designed to evaluate the performance of the ISL54400/ISL54410 device families, and can be applied to various types of clock and timing control applications in different industries. Such as Industrial Automation, Telecommunications, Automotive, Avionics, Video/Multimedia and Computer/Test/Measurement. In terms of industrial automation, the board is useful in producing a low-jitter clock to synchronize the rates at which different devices communicate with each other.

Working Principle

The ISL54400EVAL1Z board operates on the same principle as an external clock circuitry that connects to the ISL54400 devices: the oscillator performs a function of creating a square wave signal that is used to control the device’s clock rate. The board includes several reference clock oscillators in addition to evaluator connections so that the user can easily evaluate the performance of the ISL54400 device family in different clock arrangements. The oscillators are configured to output either a sine wave signal or a variable square wave signal with adjustable duty cycles and fixed transition times depending on the precise timing requirements of the application.

The board is equipped with a high speed digital synthesizer to control the frequency of the clock signals generated by the evaluator. The frequency of the clock oscillators can be independently adjusted by connecting the control inputs to the digital synthesizer. The user can input an analog signal or digital signal via a serial connection to control the frequency of the ISL54400 devices.

To further enhance performance of the ISL54400EVAL1Z board, it also includes a crystal oscillator for generating a very stable and accurate clock signal. The crystal oscillator can be adjusted by connecting it to an external reference clock source, such as a precision quartz crystal oscillator. Combined with the digital synthesizer, this ensures that the output clocks produced by the ISL54400 device family are generated with extremely low jitter.

Conclusion

The Intersil ISL54400EVAL1Z evaluation and demonstration board is an effective tool to generate reliable clock signals for clock and timing control applications in different industries. Its wide range of features, such as the adjustability of the frequency of the oscillators, crystal oscillator for increased precision and stability, and digital synthesizer to reduce clock jitter, make the board suitable for a variety of clock synchronization applications.
