2 GHz clock distribution with 2:12 fanout
The LMK1D1212RHAR: The 2:12 fanout ratio means a single device can replace multiple lower-fanout buffers on a dense timing tree, saving board space and reducing clock skew across the fan-out paths.
Input flexibility and supply rails
The input stage accepts CML, HCSL, LVCMOS, LVDS, and LVPECL signal standards, so the same buffer can interface with a wide range of clock sources without external level translation. The differential input-to-output path means the buffer preserves signal integrity for high-speed differential clocks, critical for jitter-sensitive applications like SERDES reference clocks.
