ICST ICS557-06
The ICS557-06 is a one to four differential clock buffer designed for use in PCI-Express applications. The device selects one of the two differential HCSL or LVDS input pairs and fans out to four pairs of differential HCSL or LVDS outputs. c o m ICS557-06 One to Four HCSL Clock Buffer Application Information Decoupling Capacitors As with any high-performance mixed-signal IC, the ICS557-06 must be isolated from system power supply noise to perform optimally.DESCRIPTION
