Descripción de LMK00304
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 two universal inputs or one crystal input. The selected input clock is distributed to two banks of 2 differential outputs and one LVCMOS output. The differential output banks can be mutually configured as LVPECL, LVDS, or HCSL drivers, or disabled. The LVCMOS output has a synchronous enable input for runt-pulse-free operation when enabled or disabled. The LMK00304 operates from a 3.3 V core supply and 3 independent 3.3 V/2.5 V output supplies.
The LMK00304 provides high performance, versatility, and power efficiency, making it ideal for replacing fixed-output buffer devices while increasing timing margin in the system.
