DESCRIPTION

The CDCV304 is a high-performance, low-skew, general-purpose PCI-X compliant clock buffer. It distributes one

input clock signal (CLKIN) to the output clocks (1Y[0:3]). It is specifically designed for use with PCI-X

applications. The CDCV304 operates at 3.3 V and 2.5 V and is therefore compliant to the 3.3-V PCI-X

specifications.

The CDCV304 is characterized for operation from

–40°C to 85°C for automotive and industrial applications.
