NB100LVEP222FAG

Clock Buffers, Drivers Overview

The NB100LVEP222FAG is a low skew 2:1:15 differential ÷1/÷2 ECL fanout buffer designed for clock distribution. It accepts LVECL/LVPECL input signals and provides selectable 1x or 1/2x frequency outputs across four banks (Qa, Qb, Qc, Qd). The device guarantees 20 ps output-to-output skew and 85 ps part-to-part skew. Operating in LVPECL mode requires VCC/VCC0 between 2.375 V and 3.8 V with VEE at 0 V. In NECL mode, VEE ranges from -2.375 V to -3.8 V with VCC/VCC0 at 0 V. Power supply current typically ranges from 104 mA to 168 mA depending on temperature.

Clock Buffers, Drivers Feature Summary

• Low skew performance with 20 ps output-to-output skew and 85 ps part-to-part skew
• Selectable 1x or 1/2x frequency outputs via asynchronous fsel pins
• LVPECL mode operating range of 2.375 V to 3.8 V with VEE = 0 V
• Internal VBB reference voltage output for single-ended input configurations

Clock Buffers, Drivers Applications

• High-performance clock distribution systems
• Differential ECL/PECL fanout buffering
• Data distribution applications using /C00661 mode

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'FAG' against official documentation, as the datasheet lists 'MNG' for the QFN-52 package. Confirm RoHS compliance and Pb-free status directly with the manufacturer or authorized distributors. Ensure procurement channels provide valid traceability for the assembly location and wafer lot codes indicated in the marking diagram.

Clock Buffers, Drivers Selection Notes

Select this component when low skew and high-speed differential clock distribution are required. Ensure the design supports asynchronous control inputs (fsel, CLK_Sel) and includes Master Reset (MR) circuitry to resynchronize outputs after configuration changes. Verify that the PCB layout accommodates the QFN-52 exposed pad connected to VEE for thermal management.

Clock Buffers, Drivers Part Context

The NB100LVEP222 serves as an improved version of the MC100LVE222, offering higher speed capability and reduced skew. It belongs to the NB100LVEP family of ECL devices. The device integrates 821 transistors and features internal input pulldown (75 kΩ) and pullup (37.5 kΩ) resistors to manage open input states.

Clock Buffers, Drivers Replacement Considerations

The NB100LVEP222 is explicitly identified as an improved version of the MC100LVE222. Designers should verify pin compatibility and electrical parameter improvements before substituting.
