description
The CDCV304 is a high-performance, low-skew, general-purpose and PCI-X 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.
The CDCV304 is characterized for operation from –40°C to 85°C for automotive and industrial applications.
