The Cypress CY25560 is a spread spectrum clock generator (SSCG) IC used to reduce the EMI found in today’s high-speed digital electronic systems.
The CY25560 uses Cypress’s proprietary phase-locked loop (PLL) and spread spectrum clock (SSC) technology to synthesize and frequency modulate the input frequency of the reference clock. By frequency modulating the clock, the measured EMI at the fundamental and harmonic frequencies of clock (SSCLK) is greatly reduced.
