Quad Differential PCI-Express Clock Source
Description
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.
Features
Packaged in 20-pin TSSOP
Available in Pb (lead) free 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
