DATASHEET

QUAD DIFFERENTIAL PCI-EXPRESS CLOCK SOURCE

ICS557-05A

Description

Features

The ICS557-05A is a spread-spectrum clock generator that

supports PCI-Express requirements. It is used in PC or

embedded systems to substantially reduce

electro-magnetic interference (EMI). The device provides

four differential HCSL or LVDS high-frequency outputs with

spread spectrum capability. The output frequency and

spread type are selectable using external pins.

• Packaged in 20-pin TSSOP

• Available in RoHS 5 (green) or RoHS 6 (green and lead

free) complaint package

• Supports PCI-Express applications

• Four differential spread spectrum clock outputs

• Spread spectrum for EMI reduction

• Uses external 25 MHz clock or crystal input

• Power down pin turns off chip

• OE control tri-states outputs

• Spread and frequency selection via external pins

• Spread Bypass option available

• Industrial temperature range available
