Product Overview
The CDCLVP215RHBT from Texas Instruments is a high-performance, low-jitter clock buffer with a 2:1 multiplexer input. It is designed to distribute clock signals with minimal additive phase jitter, making it ideal for demanding applications such as 5G base stations, data centers, and high-speed instrumentation. The device operates from a 2.5V or 3.3V supply and features LVPECL outputs, providing excellent signal integrity over long traces.
