NB6L14SMNTWG

Clock Buffers, Drivers Overview

The NB6L14SMNTWG is a 2.5 V differential 1:4 clock or data receiver and fanout buffer/translator from onsemi's ECLinPS MAX family. It accepts AnyLevel differential inputs including LVPECL, CML, LVDS, and HSTL, translating them to four identical LVDS outputs. Operating up to 2.0 GHz for clocks or 2.5 Gb/s for data, it features a wide input common mode range (GND + 50 mV to VCC − 50 mV) and internal 50 Ω input termination resistors. Key electrical parameters include a maximum propagation delay of 600 ps, typical RMS clock jitter of 1 ps, and a single power supply requirement of 2.5 V ± 5%. The device is housed in a 3 mm x 3 mm QFN-16 package.

Clock Buffers, Drivers Feature Summary

• Accepts AnyLevel differential inputs (LVPECL, CML, LVDS, HSTL) and translates to LVDS
• Maximum input clock frequency > 2.0 GHz; maximum data rate > 2.5 Gb/s
• Low jitter performance with 1 ps max RMS clock jitter and ~10 ps typical data dependent jitter
• Integrated synchronous output enable (EN) pin with LVTTL/LVCMOS logic levels

Clock Buffers, Drivers Applications

• SONET network synchronization
• Gigabit Ethernet (GigE) clock distribution
• Fiber Channel signal translation
• Backplane clock and data routing

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'WG' corresponds to the QFN-16 package with Pin 1 orientation in Quadrant A as specified in the datasheet. Confirm RoHS compliance and Pb-free status via manufacturer documentation. Ensure thermal management requirements for the exposed pad are met during PCB layout to maintain junction temperature within the -40°C to +85°C operating range.

Clock Buffers, Drivers Selection Notes

Select this component when interfacing between disparate high-speed logic families such as LVPECL or CML sources and LVDS destinations. The wide input common mode range simplifies biasing for capacitor-coupled signals using the VREFAC pin. Ensure the application operates within the 2.375 V to 2.625 V supply voltage range to meet AC specifications. Consider the 600 ps maximum propagation delay for timing closure in high-frequency designs.

Clock Buffers, Drivers Part Context

The NB6L14SMNTWG belongs to the NB6L14S series, which includes variants like NB6L14SMNG and NB6L14SMNTXG. These parts share identical electrical characteristics but differ in packaging quantities and tape-and-reel orientations. The NB6L14S is the 2.5 V version of the NB6N14S, designed specifically for low-voltage high-performance applications within the ECLinPS MAX portfolio.
