NB3N121K Overview
The NB3N121K is a differential 1:21 Clock and Data fanout buffer with High−speed Current Steering Logic (HCSL) outputs optimized for ultra low propagation delay variation. The NB3N121K is designed with HCSL PCI Express clock distribution and FBDIMM applications in mind. Inputs can directly accept differential LVPECL, HCSL, and LVDS signals per Figures 7, 8,.
