NB3N111KMNG

The NB3N111KMNG is a differential 1:10 clock fanout buffer from On Semiconductor, featuring High-speed Current Steering Logic (HCSL) outputs optimized for low propagation delay variation. It is designed for applications such as PCI Express clock distribution and FBDIMM memory cards.

This buffer supports input signals including LVPECL, LVDS, and HCSL, and can accept single-ended LVPECL, HCSL, LVCMOS, or LVTTL levels with an external reference supply. The device operates over a voltage range of 3.0 V to 3.6 V and a temperature range of -40°C to 85°C. Key electrical specifications include a typical input clock frequency of up to 400 MHz, typical rise and fall times of 220 ps, and a typical propagation delay of 800 ps with a maximum variation of 100 ps per differential pair.

The NB3N111KMNG offers typical HCSL output levels of 700 mV peak-to-peak and can also interface to LVDS receivers with appropriate termination. It guarantees low output-to-output skew, making it suitable for distributing low-skew clocks across backplanes or motherboards. The device is available in a 32-QFN (5x5) surface mount package.

Applications for the NB3N111KMNG include general clock distribution, PCIe I, II, III interfaces, networking equipment, high-end computing systems, routers, servers, and FBDIMM memory cards.
