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