MC10EP11DTR2

Clock Buffers, Drivers Overview

The MC10EP11DTR2 is a differential 1:2 fanout buffer from the onsemi MC10/100EP11 series, designed for high-speed clock distribution. It operates in PECL mode with VCC ranging from 3.0 V to 5.5 V (VEE = 0 V) and NECL mode with VEE from −3.0 V to −5.5 V (VCC = 0 V). The device features a typical propagation delay of 220 ps and supports maximum clock frequencies exceeding 3 GHz. It includes safety clamps on inputs and defaults Q outputs LOW when inputs are open or at VEE. The component is housed in an 8-lead TSSOP package.

Clock Buffers, Drivers Feature Summary

• Differential 1:2 fanout buffer with 220 ps typical propagation delay
• Supports PECL (3.0 V–5.5 V) and NECL (−3.0 V to −5.5 V) operating modes
• Maximum clock frequency > 3 GHz typical

Clock Buffers, Drivers Applications

• High-speed clock distribution networks
• PECL/NECL logic systems requiring fast AC performance
• Differential signal buffering in telecommunications equipment

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix 'R2' corresponds to the tape and reel shipping configuration as defined in the manufacturer's ordering information table. Confirm that the 'D' suffix indicates the SOIC-8N B package variant if required, noting that the datasheet lists MC10EP11DR2G for SOIC-8N B tape/reel and MC100EP11DTR2G for TSSOP-8 tape/reel. Ensure compliance with RoHS and Pb-Free requirements specified for the device family.

Clock Buffers, Drivers Selection Notes

Select this component when differential ECL buffering with propagation delays under 270 ps max is required. Choose based on supply voltage compatibility: use for PECL applications between 3.0 V and 5.5 V or NECL applications between −3.0 V and −5.5 V. Consider the TSSOP-8 package for surface-mount assembly where thermal management and pin count fit the design constraints. Verify input/output voltage swings against the receiver specifications.

Clock Buffers, Drivers Part Context

The MC10EP11DTR2 belongs to the MC10/100EP11 family of differential fanout buffers. It is functionally equivalent to the LVEL11 device but offers significantly faster AC performance. The '10' prefix denotes standard operating conditions, while the '100' series includes temperature compensation. This buffer serves as a critical interface component for distributing single-ended or differential clock signals to multiple downstream loads in high-frequency digital systems.

Clock Buffers, Drivers Replacement Considerations

The MC10EP11 is pin and functionally equivalent to the LVEL11 device. For direct replacements within the same family, consider the MC100EP11 variants which include temperature compensation. Verify package compatibility (SOIC-8 vs TSSOP-8) and electrical characteristics such as propagation delay and supply voltage ranges before substitution.
