2 GHz fanout buffer with flexible signal-level support
The Texas Instruments LMK1D1212RHAT is a clock buffer that distributes one of two selectable input clocks to twelve LVDS outputs, supporting a maximum frequency of 2 GHz. 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.
