General Description

The Cypress CY25568 is a spread spectrum clock generator (SSCG) IC used for the purpose of reducing electro magnetic interference (EMI) found in today's high-speed digital electronic systems.

The CY25568 uses a Cypress proprietary phase-locked loop (PLL) and spread spectrum clock (SSC) technology to synthesize and modulate the frequency of the digital clock. By frequency modulating the clock, the measured EMI at the fundamental and harmonic frequencies is greatly reduced.

Dear valued customer,

Thank you for choosing our products. They come with all the know-how and passion that our engineers have put into it. As you probably already know, Cypress is now Infineon. This is a major step for our company, but also for the good of you.
