The 2:12 fanout ratio means a single device can feed twelve downstream PLLs or SerDes transceivers from a redundant clock source, reducing component count on the board. ## Signal compatibility and supply voltage flexibility Inputs accept CML, HCSL, LVCMOS, LVDS, and LVPECL levels, so the buffer interfaces directly with most common high-speed clock sources without external level translation. All input-to-output paths are fully differential, preserving signal integrity and common-mode noise rejection at multi-gigahertz frequencies.","metaTitle":"Texas Instruments LMK1D1212RHAT Clock Buffer, 2 GHz","metaDescription":"Texas Instruments LMK1D1212RHAT clock buffer, 2 GHz max frequency, 2:12 fanout, LVDS outputs, 40-VQFN package.
