MC100E111FNG

Clock Buffers, Drivers Overview

The MC100E111FNG is a high-speed clock driver and distribution component manufactured by onsemi. It functions as a 1:9 differential fanout buffer designed for ECL logic families, specifically supporting 5V ECL operation. The device accepts a single-ended or differential input and provides nine complementary differential outputs to distribute clock signals across multiple loads. Packaged in a 28-lead Plastic Leaded Chip Carrier (PLCC), it is engineered for applications requiring precise timing distribution in high-frequency digital systems. The component operates within a specified temperature range and utilizes standard ECL voltage levels for signal integrity.

Clock Buffers, Drivers Feature Summary

• Provides 1:9 differential fanout buffering capability for ECL clock signals
• Supports 5V ECL logic family with differential input and output configurations
• Housed in a 28-lead PLCC surface-mount package for compact integration

Clock Buffers, Drivers Applications

• High-speed data communication systems requiring clock distribution
• Telecommunications infrastructure utilizing ECL logic standards
• Test and measurement equipment needing precise timing buffers

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix 'FNG' against official datasheets to confirm package type and compliance status, as suffixes often denote tape-and-reel packaging or RoHS compliance variations compared to the base model. Confirm availability status, as this part number may be subject to discontinuation or limited stock depending on the manufacturer's lifecycle announcements. Cross-reference with authorized distributors to ensure authenticity and proper handling specifications for sensitive ECL components.

Clock Buffers, Drivers Selection Notes

Select this component when a 1:9 split ratio is required for 5V ECL clock networks. Ensure the design supports the thermal dissipation requirements of the PLCC package. Verify that the system power supply aligns with standard 5V ECL negative voltage rails. Consider the propagation delay characteristics typical of this series if timing skew between outputs is critical to the application performance.

Clock Buffers, Drivers Part Context

This part belongs to the MC100E series of ECL logic devices from onsemi. It is distinct from the LVE (Low Voltage ECL) variants such as the MC100LVE111, which operate at lower voltages (3.3V). The MC100E111FNG is specifically tailored for traditional 5V ECL environments, differentiating it from newer low-power alternatives in the same functional category.

Clock Buffers, Drivers Replacement Considerations

Direct replacements include the MC100E111FN or MC100E111DTG, provided the package and termination method match the existing PCB layout. For low-voltage upgrades, the MC100LVE111FN offers similar functionality but requires voltage level translation and pin compatibility verification.
