Four Output PCI-X and
General Purpose Buffer
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 3.3 V and outputs can run up to 140 MHz.
■
General-purpose or PCI-X clock buffer
■
Buffers all frequencies from DC to 140 MHz
■
Output-to-output skew less than 100 ps
■
Space-saving 8-pin TSSOP package
■
3.3 V operation
■
60 ps typical output-output skew
