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.
