Overview
The CDCV304PW is a high-performance, low-skew, general-purpose PCI-X compliant clock buffer produced by Texas Instruments. This component is designed to distribute one input clock signal (CLKIN) to four output clocks (1Y[0:3]), making it ideal for use in PCI-X applications. The CDCV304PW operates at both 3.3 V and 2.5 V supply voltages, ensuring compliance with the 3.3-V PCI-X specifications. It is characterized for operation over a temperature range of –40°C to 85°C, making it suitable for automotive and industrial applications.
