기능 설명

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.
