MC10E111FNG

Clock Buffers, Drivers Overview

The MC10E111FNG 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 Q outputs LOW and Q-bar outputs HIGH. It operates in PECL mode with VCC ranging from 4.2 V to 5.7 V (VEE = 0 V) or NECL mode with VCC at 0 V and VEE from -4.2 V to -5.7 V. The component features internal 50 kΩ input pulldown resistors and ESD protection exceeding 3 kV via the Human Body Model.

Clock Buffers, Drivers Procurement Notes

Verify RoHS compliance status as historical data indicates non-compliance for standard versions; confirm if Pb-free variants are required. Check current lifecycle status as the part may be obsolete or subject to production changes. Ensure supply chain sources provide valid datasheets matching Rev 16 or later. Confirm package integrity for PLCC-28 housing during procurement.

Clock Buffers, Drivers Selection Notes

Select this component when a 1:9 differential fanout buffer is required with guaranteed skew performance. Choose between PECL and NECL operating modes based on system power supply constraints (4.2–5.7 V vs. -4.2 to -5.7 V). Ensure the application supports single-ended inputs only if the VBB pin is properly biased. Verify that the 28-pin PLCC package fits the PCB layout constraints.

Clock Buffers, Drivers Part Context

The MC10E111 belongs to the MC10E/100E series of ECL logic devices from onsemi. It is functionally similar to other 1:9 drivers in the family but distinguished by its specific skew guarantees and enable logic. The 'FN' suffix denotes the PLCC-28 package variant. It serves as a critical timing element in systems requiring signal splitting with minimal phase deviation.

Clock Buffers, Drivers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate MC10E111FNG equivalents from other manufacturers only if they match the 1:9 differential ECL specification, PLCC-28 package, and voltage ranges. Verify functional compatibility before substitution.
