MC100EL11DT

Clock Buffers, Drivers Overview

The MC100EL11DT is a differential 1:2 fanout buffer from the onsemi 100EL series, designed for high-speed clock distribution. It operates in PECL mode with VCC between 4.2 V and 5.7 V (VEE = 0 V) or NECL mode with VEE between −4.2 V and −5.7 V (VCC = 0 V). The device features a maximum propagation delay of 340 ps at 25°C and within-device skew of 5 ps. It includes internal input pulldown resistors to maintain stability under open input conditions. Packaged in an SOIC-8 surface-mount case, it supports operating temperatures from −40°C to +85°C.

Clock Buffers, Drivers Feature Summary

• Differential 1:2 fanout buffer with 265 ps typical propagation delay
• 5 ps within-device skew between outputs
• Supports PECL (4.2–5.7 V) and NECL (−4.2 to −5.7 V) power supply configurations
• Internal input pulldown resistors prevent instability when inputs are left open

Clock Buffers, Drivers Applications

• High-speed clock distribution networks
• PECL/NECL logic interfacing
• Differential signal buffering in telecommunications equipment

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix 'DT' against the manufacturer's current documentation, as the datasheet lists 'DG' and 'DR2G' variants for the SOIC-8 package. Confirm availability status directly with onsemi or authorized distributors, as some suffixes may indicate discontinued or restricted production runs. Ensure the procurement channel provides valid RoHS compliance documentation.

Clock Buffers, Drivers Selection Notes

Select the MC100EL11DT when low skew and fast propagation delay are critical for differential clock signals. Choose this component over the standard 10EL series if improved performance metrics such as reduced jitter and skew are required. Ensure the system design accommodates the specified PECL or NECL voltage ranges and thermal requirements for the SOIC-8 package.

Clock Buffers, Drivers Part Context

The MC100EL11 is part of the 100EL family, which offers enhanced performance compared to the legacy E111 device. It is functionally similar to other members of the MC10EL/100EL series but optimized for lower skew and faster switching speeds. The device is manufactured by onsemi and falls under the category of ECL fanout buffers.

Clock Buffers, Drivers Replacement Considerations

The MC10EL11 is a functional equivalent within the same family but may exhibit slightly higher propagation delay. Verify pin compatibility and electrical specifications before substitution. Contact onsemi for recommendations on newer alternatives if the MC100EL11DT is no longer recommended for new designs.
