ASM2P2304NZ

Four Output PCI-X and General Purpose Buffer

Functional Description

Features

•

One input to four Output Buffer/Driver

The ASM2P2304NZ 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

Output-to-output skew less than 100 pS

Available in 8-pin TSSOP and SOIC Packages
