NB4N111K: Clock Fanout Buffer, 1:10 Differential, 3.3 V, with HCSL Level Output
Product Description
The NB4N111K is a differential input clock 1 to 10 HCSL fanout buffer, optimized for ultra low propagation delay variation. The NB4N111K is designed with HCSL clock distribution for FBDIMM applications in mind. Inputs can accept differential LVPECL, CML, or LVDS levels. Single-ended LVPECL, CML, LVCMOS or LVTTL levels are accepted with the proper VREFAC supply (see Figures 5, 10, 11, 12, and 13). Clock input pins incorporate an internal 50 ohm on die termination resistors.
