The LMK00334 device is a 4-output HCSL fanout buffer intended for high-frequency,low-jitter clock, data distribution, and level translation. The input clock can be selected fromtwo universal inputs or one crystal input. The selected input clock is distributed to two banks of2 HCSL outputs and one LVCMOS output. The LVCMOS output has a synchronous enable input forrunt-pulse-free operation when enabled or disabled. The LMK00334 operates from a 3.3-V core supplyand 3 independent 3.3-V or 2.5-V output supplies.

The LMK00334 provides high performance, versatility, and power efficiency, making itideal for replacing fixed-output buffer devices while increasing timing margin in thesystem.
