IMIFS784 Overview
The Cypress FS781/82/84 are Spread Spectrum clock generator ICs (SSCG) designed for the purpose of reducing electromagnetic interference (EMI) found in today’s high-speed digital systems. The FS781/82/84 SSCG clocks use a Cypress-proprietary technology to modulate the input clock frequency, XIN, by modulating the frequency of the digital clock. By modulating the reference clock the measured EMI at the fundamental...
