Radiation Tolerant Quad Clock Output Demonstration Board

The ISL74420MDEMO1Z radiation tolerant quad clock fanout IC demonstration board features the plastic version of the ISL74420M. The ISL74420MDEMO1Z is an example of a small-footprint layout with SMD resistors for user-defined power-up configuration.

This board is functionally similar to the ISL74420MEV1Z, which has mechanical configuration switches for easier experimentation with frequency and delay selections. Both versions of the ISL74420M boards support I²C interface, allowing override of the power-up pin-selected configuration.

Before starting an evaluation, please review the ISL74420M datasheet for detailed information about operation, function, and performance, including detailed I²C specifications, helpful links to software tools, and approaches for writing to and reading from the device registers.

The ISL74420MDEMO1Z demonstration board and accompanying manual provide a physical and electrical method to evaluate the stand-alone operation of the ISL74420M.
