Product Overview
The CDCLVD1213RGTT is a high-performance, low-jitter clock buffer from Texas Instruments, designed to distribute clock signals with minimal skew and additive phase jitter. It features a 2:12 LVDS fanout configuration, accepting two differential clock inputs and providing twelve LVDS outputs. The device operates from a single 1.8V, 2.5V, or 3.3V supply and is housed in a compact 16-pin VQFN (3x3 mm) package. It is ideal for applications requiring precise clock distribution, such as 5G base stations, data centers, and automotive infotainment systems.
