SY100E111AJY-TR

Clock Buffers, Drivers Overview

The SY100E111AJY-TR is a low skew 1-to-9 differential clock driver manufactured by Microchip Technology. It operates with 5V or 3.3V power supplies and accepts one signal input, which can be differential or single-ended using the VBB output. The device fans out the signal to nine identical differential outputs. Key specifications include a part-to-part skew of 200ps and an output-to-output skew of 50ps. It features voltage and temperature compensated outputs, internal 75KΩ input pulldown resistors, and a VBB reference output. The component is housed in a 28-pin PLCC package.

Clock Buffers, Drivers Feature Summary

• Low skew design with 200ps part-to-part skew and 50ps output-to-output skew
• Supports both 5V and 3.3V power supply options for ECL and PECL modes
• Provides nine differential outputs from a single differential or single-ended input
• Includes internal 75KΩ input pulldown resistors and a VBB reference output

Clock Buffers, Drivers Applications

• High-performance clock distribution across backplanes
• Board-level clock distribution systems
• Systems requiring low jitter and tight skew margins

Clock Buffers, Drivers Procurement Notes

Verify the Pb-Free status indicated by the 'JY' suffix and the tape-and-reel packaging specified by '-TR'. Confirm that the industrial temperature range (-40°C to +85°C) meets system requirements. Ensure proper termination of unused differential pairs on the same package side as active pairs to maintain minimum skew specifications.

Clock Buffers, Drivers Selection Notes

Select this component when a 1:9 fanout ratio is required with strict skew constraints. It is suitable for designs needing compatibility with Motorola MC100LVE111 standards. Consider the 28-pin PLCC package size and moisture sensitivity level 1 rating during PCB layout and assembly planning.

Clock Buffers, Drivers Part Context

This part belongs to the Precision Edge SY10/100E111A/L series, designed specifically for low skew performance. It improves upon the standard SY10/100E111 by offering lower jitter and low voltage operation capabilities. The device is fully compatible with industry standard 10KH and 100K ECL levels.

Clock Buffers, Drivers Replacement Considerations

The datasheet states full compatibility with the Motorola MC100LVE111. Designers may consider this equivalent for direct replacement in existing designs without functional modification.
