DESCRIPTION  
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.
