Product Overview
The CDCLVD1204RGTR from Texas Instruments is a high-performance, low-jitter LVDS clock buffer designed for distributing clock signals in demanding applications. It features four differential outputs, each capable of driving 50-ohm transmission lines, with an operating frequency range up to 1.5 GHz. The device operates from a 2.5V or 3.3V power supply and is housed in a compact 16-pin VQFN (3x3 mm) package, making it ideal for space-constrained designs.
