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 105°C.
