NB6N14SMNR2G

Clock Buffers, Drivers Overview

The NB6N14SMNR2G is a differential 1:4 clock or data receiver and fanout buffer/translator manufactured by onsemi. It accepts AnyLevel/C0116 differential input signals, including LVPECL, CML, or LVDS, and translates them to four identical LVDS outputs. The device operates at maximum input clock frequencies up to 2.0 GHz and supports data rates up to 2.5 Gb/s. Key electrical parameters include a maximum propagation delay of 600 ps, a typical propagation delay of 380 ps, and a maximum RMS clock jitter of 1 ps. It functions within a supply voltage range of 3.0 V to 3.6 V and is housed in a 3 mm x 3 mm QFN-16 package.

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'R2G' corresponds to the Tape & Reel shipping configuration containing 3000 units per reel. Confirm the component is Pb-Free as indicated by the datasheet specifications. Ensure the QFN-16 package dimensions match the required PCB footprint for thermal management via the exposed pad.

Clock Buffers, Drivers Selection Notes

Select this component when translating various differential signal standards to LVDS with low jitter requirements. The wide input common mode range from GND + 50 mV to VCC − 50 mV allows flexibility in interfacing with different driver types. Verify that the 3.3 V supply voltage aligns with the system design constraints.

Clock Buffers, Drivers Part Context

This part belongs to the NB6N14S family, which is part of the ECLinPS MAX high-performance product line. The NB6N14S variant specifically provides a 1:4 fanout ratio. Other variants in the series may offer different fanout ratios or performance characteristics, but this specific model is optimized for 2.0 GHz operation.

Clock Buffers, Drivers Replacement Considerations

The NB6L14SMNTXG is a functionally compatible alternative within the same family, offering similar LVDS translation capabilities. Both devices share the QFN-16 package and operate on 3.3 V supplies. Verify specific timing parameters and input/output configurations before substitution.
