MC100LVE111FN

Clock Buffers, Drivers Overview

The MC100LVE111FN is a low-voltage ECL (LVECL) clock fanout buffer manufactured by onsemi. It provides a 1:9 input-to-output ratio, distributing a single differential input signal to nine differential outputs. The device supports maximum frequencies up to 1.5 GHz and operates within a supply voltage range of 3V to 3.8V. Packaged in a 28-PLCC (J-Lead) surface-mount format, it is designed for high-speed clock distribution applications requiring low voltage operation.

Clock Buffers, Drivers Feature Summary

• 1:9 Differential Fanout Ratio
• Maximum Frequency of 1.5 GHz
• Supply Voltage Range: 3V to 3.8V
• 28-LCC (J-Lead) Package

Clock Buffers, Drivers Applications

• High-speed clock distribution networks
• Low-voltage ECL system timing
• PECL/LVECL interface buffering

Clock Buffers, Drivers Procurement Notes

Verify component status as the MC100LVE111FN is listed as obsolete or discontinued by the manufacturer. Check for RoHS compliance status, which may be non-compliant depending on production date. Confirm availability through authorized distributors or surplus channels, noting that standard factory packaging quantities may apply to remaining stock.

Clock Buffers, Drivers Selection Notes

Select this component when a 1.5 GHz LVECL fanout buffer with 9 outputs is required. Ensure the design supports the 3V–3.8V supply range. For higher frequency requirements exceeding 1.5 GHz, consider the MC100LVEP111 series which supports up to 3 GHz. Verify package compatibility with the 28-PLCC footprint during PCB layout.

Clock Buffers, Drivers Part Context

Part of the onsemi 100LVE series, which focuses on low-voltage ECL solutions. This series offers temperature compensation and AC performance comparable to older 5V ECL devices while consuming less power. The MC100LVE111FN specifically addresses the need for multi-point clock distribution in lower voltage environments.

Clock Buffers, Drivers Replacement Considerations

The MC100LVEP111FAG is a functional alternative offering similar 1:10 distribution capabilities but with a higher maximum frequency of 3 GHz and an LQFP-32 package. Note that pinouts and package dimensions differ between the PLCC and LQFP formats.
