MC100ES6254ACR2

Clock Buffers, Drivers Overview

The MC100ES6254ACR2 is a bipolar monolithic differential 2x2 clock switch and fanout buffer manufactured by Renesas Electronics Corporation. It utilizes SiGe technology to support LVPECL signals from DC to 3 GHz with a maximum propagation delay of 610 ps and device skew of 50 ps. The component operates on a single 2.5 V or 3.3 V supply, features synchronous output enable, and includes six differential outputs across two banks. It is housed in a standard 32-lead LQFP package.

Clock Buffers, Drivers Feature Summary

• SiGe technology enables near-zero output skew (50 ps max) and supports DC to 3 GHz operation
• Fully differential architecture from input to all outputs for superior signal characteristics
• Configurable as a 2x2 clock switch, dual 1:3 buffer, or single 1:6 fanout buffer
• LVCMOS compatible control inputs with synchronous output enable to prevent runt pulses

Clock Buffers, Drivers Applications

• High-performance clock/data switching in computing systems
• Clock distribution and data loopback in networking equipment
• On-board clocking for OC-3, OC-12, and OC-48 communication systems

Clock Buffers, Drivers Procurement Notes

Verify the discontinuance status, as the original manufacturer IDT issued a notice with a last time buy date of December 7, 2013. Confirm current availability through Renesas Electronics Corporation distributors. Ensure the ordering suffix 'ACR2' matches the required LQFP-32 Pb-free tape and reel packaging configuration.

Clock Buffers, Drivers Selection Notes

Select this component for applications requiring precise alignment of differential clock signals with minimal skew. Ensure the design accommodates a single 2.5 V or 3.3 V positive supply without negative rails. Verify that the PCB thermal management can maintain the junction temperature within the specified functional range of -40°C to +110°C.

Clock Buffers, Drivers Part Context

This part belongs to the MC100ES6254 family of differential clock switches. It was originally developed by Integrated Device Technology (IDT) before being acquired by Renesas Electronics Corporation. The AC suffix denotes the industrial temperature grade and specific performance characterization limits defined in the datasheet.

Clock Buffers, Drivers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the product discontinuance notice, alternative components must be evaluated based on pin compatibility, LVPECL specifications, and skew requirements.
