Description
QUAD DIFFERENTIAL PCI-EXPRESS GEN1 CLOCK SOURCE DATASHEET ICS557-05A .
Features
The ICS557-05A is a spread-spectrum clock generator that supports PCI-Express requirements.
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. Th
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
