MC10E111FNR2G

Clock Buffers, Drivers Overview

The MC10E111FNR2G is a low skew 1-to-9 differential clock driver manufactured by onsemi. Designed for high-speed clock distribution, it accepts one signal input, which can be differential or single-ended when the VBB output is utilized. The device fans out the signal to nine identical differential outputs and includes an enable input that disables the device by forcing all Q outputs LOW and all Q_bar outputs HIGH when set to HIGH. It operates in PECL mode with VCC ranging from 4.2 V to 5.7 V and VEE at 0 V, or in NECL mode with VCC at 0 V and VEE from −4.2 V to −5.7 V.

Clock Buffers, Drivers Feature Summary

• Low skew 1-to-9 differential clock driver architecture
• Supports both PECL (VCC 4.2–5.7 V) and NECL (VEE −4.2 to −5.7 V) operating modes
• Internal 50 kΩ input pulldown resistors for single-ended compatibility
• ESD protection exceeding 3 kV per Human Body Model standard

Clock Buffers, Drivers Applications

• High-speed clock distribution networks
• PECL/NECL compatible digital systems
• Multi-point clock fan-out applications

Clock Buffers, Drivers Procurement Notes

Verify RoHS compliance status and Moisture Sensitivity Level (MSL 3) before procurement. Confirm package type is PLCC-28 and mounting style is SMD/SMT. Check for Pb-free designation as standard packages are available. Ensure ordering suffix matches required reel quantity of 500 units.

Clock Buffers, Drivers Selection Notes

Select this component for applications requiring precise timing skew across multiple clock lines. Ensure supply voltage aligns with either PECL or NECL specifications. Verify that the 28-lead PLCC package fits the PCB layout constraints. Consider the enable pin functionality for power management requirements.

Clock Buffers, Drivers Part Context

This part belongs to the MC10E/100E series of ECL logic devices. It is functionally equivalent to the MC10E111FN and MC10E111FNG variants, differing primarily in packaging and reel configuration. The FNR2G suffix indicates a specific tape and reel packaging option for automated assembly.

Clock Buffers, Drivers Replacement Considerations

Direct substitutes include MC10E111FN and MC10E111FNG. Verify pinout compatibility and electrical parameters match exactly before substitution.
