2 GHz fanout buffer with multiplexer — what it does on the board
The Texas Instruments CDCLVP1204RGTR is a 2:4 fanout buffer with an integrated 2:1 multiplexer on the input side, built to distribute high-frequency clocks up to 2 GHz. It accepts any of four common signal standards — LVCMOS, LVDS, LVPECL, or LVTTL — and outputs LVPECL, making it a single-component translation and fanout node for boards that mix logic families. The 2:4 ratio means you can select one of two input sources and distribute it to four output paths, which saves a separate mux IC in multi-reference clock trees.
Supply range is 2.375 V to 3.6 V.
Lifecycle and compliance — no obsolescence worry
For a production BOM, this means no forced redesign from a discontinued clock buffer — one less component to watch for PCNs.
