NB3N111K
3.3V Differential 1:10 Fanout Clock Driver with HCSL Outputs
Description The NB3N111K is a differential 1:10 Clock fanout buffer with
High−speed Current Steering Logic (HCSL) outputs optimized for ultra low propagation delay variation. The NB3N111K is designed with PCI Express HCSL clock distribution and FBDIMM applications in mind.
Inputs can directly accept differential LVPECL, LVDS, and HCSL signals per Figures 7, 8, and 9. Single−ended LVPECL, HCSL, LVCMOS, or LVTTL levels are accepted with a proper external Vth reference supply per Figures 4 and 10. Input pins incorporate separate internal 50 W termination resistors allowing additional single ended system interconnect flexibility.
