CY24292

Four Outputs PCI-Express Clock Generator

Features

Functional Description

■ 25 MHz Crystal or Clock Input

CY24292 is a clock generator device intended for PCI-Express

applications. The device includes: four 100 MHz differential

clocks with HCSL Compatible outputs for PCI-Express, and one

single-ended 25 MHz output.

■ Four Differential 100 MHz PCI-Express Clocks

■ Supports HCSL Compatible Output Levels

■ One Single-ended 25 MHz Output

Using a serially programmable SMBus interface, the CY24292

incorporates spread spectrum modulation on all four 100 MHz

■ Spread Spectrum Capability on all 100 MHz PCI-Express Clock

Outputs

outputs. The device incorporates a Lexmark Spread Spectrum

profile for maximum electromagnetic interference (EMI)

reduction. The spread feature or individual outputs can also be

disabled using the SMBus interface.

■ SMBus Interface with Read Back Capability

■ 32-pin QFN Package
