NB7L1008MMNTWG

Clock Buffers, Drivers Overview

The NB7L1008MMNTWG is a high-performance clock fanout buffer manufactured by onsemi, belonging to the GigaComm series. It features a single differential input and eight true differential outputs, supporting data rates up to 8 GHz. The device accepts multiple input standards including CML, LVCMOS, LVDS, LVPECL, and LVTTL, with internal termination for simplified design. Powered by a single supply voltage ranging from 2.375 V to 3.6 V, it operates within a temperature range of -40°C to 85°C. The component is housed in a compact 32-VFQFN package with exposed pad, measuring 5 mm x 5 mm, suitable for dense surface-mount applications.

Clock Buffers, Drivers Feature Summary

• Supports 1:8 fanout ratio with low skew performance for high-speed clock distribution
• Multi-level inputs with internal termination compatible with CML, LVCMOS, LVDS, LVPECL, and LVTTL
• Operates on a single 2.375 V to 3.6 V power supply
• Available in a 32-pin VFQFN (5x5 mm) package with exposed thermal pad

Clock Buffers, Drivers Applications

• High-speed serial link clock distribution
• Data converter clocking systems
• Telecommunications infrastructure timing networks

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix 'NTW' against official onsemi documentation to confirm tape and reel packaging details. Confirm current availability status as inventory levels fluctuate. Ensure compliance with RoHS and REACH regulations required for the target market. Cross-reference the DigiKey part number ending in ND for accurate ordering information.

Clock Buffers, Drivers Selection Notes

Select this component when an 8-channel differential output is required from a single differential or single-ended source. The internal termination eliminates external resistors for CML/LVPECL inputs. Verify that the 8 GHz maximum frequency meets the system's clock speed requirements. Ensure the PCB layout supports the 32-VFQFN package thermal dissipation needs via the exposed pad.

Clock Buffers, Drivers Part Context

This part is part of the NB7L1008M family of low skew clock buffers. Variants such as NB7L1008MNG and NB7L1008MMNR4G share identical electrical specifications but differ in packaging and shipping methods. The MMNTWG designation specifically indicates the QFN package configuration and tape-and-reel delivery format used for automated assembly processes.

Clock Buffers, Drivers Replacement Considerations

Direct substitutes include NB7L1008MNG and NB7L1008MMNR4G, which offer identical pinouts and electrical characteristics. Verify that the replacement variant matches the required packaging type (tube vs. reel) for the manufacturing line.
