The LMK00301 is a 3-GHz, 10-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 5 differential outputs and one LVCMOS output. Both differential output banks can be independently 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 LMK00301 operates from a 3.3 V core supply and 3 independent 3.3 V/2.5 V output supplies.
The LMK00301 provides high performance, versatility, and power efficiency, making it ideal for replacing fixed-output buffer devices while increasing timing margin in the system.
The LMK00301A is nearly identical to the LMK00301, but does not have power supply sequencing requirements between the core and output supply domains.
