NB7L14MN1TXG

Clock Buffers, Drivers Overview

The NB7L14MN1TWG is a differential 1:4 LVPECL fanout buffer from the GigaComm family, manufactured by onsemi. It generates four identical LVPECL output copies of clock or data signals operating up to 7 GHz or 10.7 Gb/s. The device features multi-level inputs with internal 50-ohm termination resistors accessed via the VT pin, allowing compatibility with LVPECL, CML, LVDS, LVCMOS, and LVTTL standards. It operates within a supply voltage range of 2.375 V to 3.6 V at +25°C (−40°C to +85°C ambient). Key electrical parameters include a typical propagation delay of 165 ps, maximum output skew of 15 ps, and less than 0.8 ps RMS clock jitter.

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix '1TWG' against the manufacturer's official documentation to confirm tape and reel packaging specifications. Ensure that the QFN-16 exposed pad is electrically connected to device ground and thermally attached to a heat-sinking conduit as required for proper operation.

Clock Buffers, Drivers Selection Notes

Select this component when low output skew and high-speed differential buffering are required for LVPECL systems. The internal termination simplifies interface design for various logic standards. Verify that the application environment maintains transverse airflow greater than 500 lfpm to ensure thermal equilibrium and specification compliance.
