Functional Description

The CY25701 is a Spread Spectrum Crystal Oscillator (SSXO) IC used to reduce the EMI found in today’s high speed digital electronic systems.

The device uses a Cypress proprietary PLL and Spread Spectrum Clock (SSC) technology to synthesize and modulate the frequency of the embedded input crystal. By frequency modulating the clock, the measured EMI at the fundamental and harmonic frequencies are 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.
