Cypress CY2304NZZXC-1T Four output pci-x and general purpose buffer Datasheet

CY2304NZ
Four Output PCI-X and General Purpose Buffer
Features
Functional Description
• One input to four output buffer/driver
The CY2304NZ is a low-cost buffer designed to distribute
high-speed clocks for PCI-X and other applications. The
device operates at 3.3V and outputs can run up to 140 MHz.
• General-purpose or PCI-X clock buffer
• Buffers all frequencies from DC to 140 MHz
