Texas Instruments LMK00304SQE/NOPB
The LMK00304 is a 3-GHz 4-output differential fanout buffer intended for high-frequency,low-jitter clock/data distribution and level translation. The input clock can be selected from twouniversal inputs or one crystal input. The selected input clock is distributed to two banks of 2differential outputs and one LVCMOS output. The differential output banks can be mutuallyconfigured as LVPECL, LVDS, or HCSL drivers, or disabled. The LVCMOS output has a synchronousenable input for runt-pulse-free operation when enabled or disabled. The LMK00304 operates from a3.3 V core supply and 3 independent 3.3 V/2.5 V output supplies.
The LMK00304 provides high performance, versatility, and power efficiency, making itideal for replacing fixed-output buffer devices while increasing timing margin in thesystem.
