Overview

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.

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
