Risks should be avoided in EMC-compliant design. It has to be ruled out that interference threatens the integrity of data communication - especially for data transmission via USB. EMC is not "nice to have" or used to satisfy regulations and standards, but is a quality feature. In order that EMC problems can be reliably excluded as early as in design, there are components tailored to the special conditions of fast data lines, which reduce the development workload and, above all, avoid reworks following critical EMC test results.
