CY25561 Datasheet Spread Spectrum Clock Generator

Manufacturer: Cypress (now Infineon)

Overview: CY25561 Spread Spectrum Clock Generator Spread Spectrum Clock.

General Description

CY25561 is a spread spectrum clock generator (SSCG) IC used to reduce electromagnetic Interference (EMI) found in today’s high speed digital electronic systems.

CY25561 uses a Cypress proprietary phase-locked loop (PLL) and spread spectrum clock (SSC) technology to synthesize and frequency modulate the input frequency of the reference clock.

By doing this, the measured EMI at the fundamental and harmonic frequencies of clock (SSCLK) is reduced.

Key Features

  • 50 to 166 MHz operating frequency range.
  • Wide range of spread selections: 9.
  • Accepts clock and crystal inputs.
  • Low power dissipation.
  • 70 mW - Typ at 66 MHz.
  • Frequency spread disable function.
  • Center spread modulation.
  • Low cycle-to-cycle jitter.
  • 8-pin SOIC Package Functional.
