250 MHz fanout buffer for clock distribution
The Texas Instruments LMK1C1104PWR is a 1:4 fanout buffer that takes a single LVCMOS input and distributes it to four LVCMOS outputs, rated to 250 MHz. It is designed for clock-tree fanout in systems where a clean, low-skew copy of a reference clock is needed across multiple loads — FPGAs, ASICs, ADCs, or Ethernet PHYs.
That means the same part works across a 1.8 V, 2.5 V, or 3.3 V logic domain without a separate level translator — useful when the clock source and the loads live on different supply planes.
