NB7L14MNTXG

Clock Buffers, Drivers Overview

The NB7L14MNTXG is a differential 1:4 LVPECL fanout buffer from onsemi, designed for clock and data distribution in high-speed applications. It operates with a supply voltage range of 2.375 V to 3.6 V and supports input clock frequencies up to 8 GHz or data rates up to 11 Gbps. The device features internal 50 Ω input termination resistors accessed via the VT pin, allowing compatibility with multiple logic standards including LVPECL, CML, LVDS, LVCMOS, and LVTTL. Key electrical parameters include a typical propagation delay of 165 ps, maximum output skew of 15 ps, and maximum RMS clock jitter of 0.8 ps. It is housed in a QFN-16 package.

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'TXG' corresponds to the QFN-16 package shipped in tape and reel format containing 3000 units per reel. Confirm RoHS compliance and Pb-free status as indicated by the 'G' suffix or microdot marking. Ensure the specific device code matches the required assembly location and wafer lot information for traceability purposes.

Clock Buffers, Drivers Selection Notes

Select this component when a low-skew, high-performance differential fanout buffer is required for LVPECL systems. The internal termination simplifies interface design for various logic levels such as CML and LVDS. Ensure the application environment stays within the -40°C to +85°C operating temperature range and that the power supply voltage remains between 2.375 V and 3.6 V for optimal performance.
