Spread Spectrum Clock Generator

for EMI Reduction

Field and Factory Programmable Spread Spectrum Clock Generator for EMI Reduction

Features

Functional Description

■ Wide Operating Output (SSCLK) Frequency Range

❐ 3 MHz to 200 MHz

The CY25100 is a Spread Spectrum Clock Generator (SSCG) IC

used to reduce EMI found in today’s high speed digital electronic

systems.

■ Programmable Spread Spectrum with nominal 31.5 kHz

The device uses a Cypress proprietary PLL and Spread

Spectrum Clock (SSC) technology to synthesize and modulate

the frequency of the input clock. By frequency modulating the

clock, the measured EMI at the fundamental and harmonic

frequencies are greatly reduced. This reduction in radiated

energy can significantly reduce the cost of complying with

regulatory agency (EMC) requirements and improve

time-to-market without degrading system performance.

Modulation Frequency

❐ Center Spread: ±0.25% to ±2.5%

❐ Down Spread: –0.5% to –5.0%

■ Input frequency range

❐ External Crystal: 8 to 30 MHz Fundamental Crystals

❐ External Reference: 8 to 166 MHz Clock

■ Integrated Phase-Locked Loop (PLL)

■ Field Programmable devices available

■ Programmable Crystal Load Capacitor Tuning Array

■ Low Cycle-to-cycle Jitter

The CY25100 uses

factory or field-programmable

configuration memory array to synthesize output frequency,

spread percentage, crystal load capacitor, reference clock output

on/off, spread spectrum on/off function, and PD#/OE options.

The spread percentage is programmed to either center spread

or down spread with various spread percentages. The range for

center spread is from ±0.25% to ±2.50%. The range for down

spread is from –0.5% to –5.0%.

■ Spread Spectrum on/off function

■ Powerdown or Output Enable function

■ Commercial and Industrial temperature ranges

■ 3.3 V operation

The input to the CY25100 can either be a crystal or a clock

signal. The CY25100 has two clock outputs: REFCLK and

SSCLK. The non-spread spectrum REFCLK output has the

same frequency as the input of the CY25100.
