機能説明

The CY25811/12/14 products are Spread Spectrum Clock Generator (SSCG) ICs used for the purpose of reducing electromagnetic interference (EMI) found in today’s high speed digital electronic systems.

The devices use a Cypress proprietary phase-locked loop (PLL) and Spread Spectrum Clock (SSC) technology to synthesize and modulate the frequency of the input clock. By frequency modulating the clock, the measured EMI at the fundamental and harmonic frequencies is greatly reduced.
