SY100E111AJI-TR

Clock Buffers, Drivers Overview

The SY100E111AJI-TR is a low skew 1-to-9 differential clock driver from the Precision Edge series, designed for high-performance clock distribution. It accepts one signal input and fans it out to nine identical differential outputs. The device supports both 5V and 3.3V power supply options, operating in PECL mode with VEE grounded. Key electrical parameters include a typical part-to-part skew of 200ps and output-to-output skew of 50ps. Propagation delay ranges from 430ps to 680ps depending on input configuration. It features voltage and temperature compensated outputs, a VBB reference output, and 75KΩ input pulldown resistors.

Clock Buffers, Drivers Feature Summary

• Low skew design with 50ps output-to-output skew and 200ps part-to-part skew
• Supports 5V (4.2V–5.5V) and 3.3V (3.0V–3.8V) power supplies
• 1:9 differential fanout buffer with VBB output for single-ended compatibility
• Fully compatible with Motorola MC100LVE111 specifications

Clock Buffers, Drivers Applications

• High performance clock distribution across backplanes
• Board-level clock distribution in +5V/+3.3V systems
• Systems requiring low jitter and tight skew margins

Clock Buffers, Drivers Procurement Notes

Verify component authenticity through authorized Microchip or Micrel distributors. Confirm RoHS compliance status as the datasheet indicates Sn-Pb lead finish for this specific suffix variant. Check for moisture sensitivity level 1 requirements during storage and handling. Ensure ordering suffix matches the required package type and temperature range.

Clock Buffers, Drivers Selection Notes

Select this component when low skew is critical for clock distribution networks. Ensure termination resistors are applied to all unused differential pairs on the same package side as active outputs to maintain specified skew performance. Verify that the system operates within the 3.3V or 5V PECL voltage ranges. Consider the 28-pin PLCC package constraints for PCB layout.

Clock Buffers, Drivers Part Context

This part belongs to the Precision Edge SY10/100E111A/L family, originally manufactured by Micrel, Inc., which was later acquired by Microchip Technology. The '100' prefix typically denotes industrial temperature range variants compared to the '10' series. The 'AJI' suffix specifies the industrial temperature range (-40°C to +85°C) and 28-pin PLCC package with tin-lead finish.

Clock Buffers, Drivers Replacement Considerations

The datasheet explicitly states full compatibility with the Motorola MC100LVE111. Designers may consider equivalent parts from other manufacturers that meet the same 1:9 differential fanout and low skew specifications, provided pinouts and electrical characteristics align.
