SY10E111LJC

Clock Buffers, Drivers Overview

The SY10E111LJC is a low skew 1-to-9 differential clock driver from the Precision Edge® series, manufactured by Micrel (now Microchip Technology). It operates in both ECL and PECL modes with supply voltages of -5V/-3.3V or +5V/+3.3V. The device features a 28-pin PLCC package and includes internal 75KΩ input pulldown resistors. Key performance metrics include a typical part-to-part skew of 200ps and output-to-output skew of 50ps. It accepts one signal input and fans it out to nine identical differential outputs without an enable function.

Clock Buffers, Drivers Feature Summary

• Low skew design with 200ps part-to-part and 50ps output-to-output skew
• Supports 5V and 3.3V power supply options for ECL and PECL applications
• Includes VBB output for single-ended input compatibility
• Features internal 75KΩ input pulldown resistors

Clock Buffers, Drivers Applications

• High-performance clock distribution on backplanes
• Board-level clock distribution systems
• Differential clock buffering in ECL/PECL environments

Clock Buffers, Drivers Procurement Notes

Verify component authenticity as this part may be obsolete or superseded. Confirm RoHS compliance status, as standard versions use Sn-Pb leads while Pb-free variants carry specific markings. Check current manufacturer availability and lead times before procurement planning.

Clock Buffers, Drivers Selection Notes

Select the L suffix variant for low voltage (3.3V) operation. Ensure proper termination of all unused differential pairs to maintain specified skew performance. Verify that the 28-pin PLCC package fits the target PCB footprint and soldering profile requirements.

Clock Buffers, Drivers Part Context

This component belongs to the Precision Edge® SY10/100E111 family, designed for minimal gate-to-gate skew. The 'L' designation indicates support for lower voltage operation compared to the 'A' series. It serves as a high-speed clock buffer for distributing signals across multiple loads.

Clock Buffers, Drivers Replacement Considerations

The datasheet notes full compatibility with Motorola MC100LVE111. Consider checking for direct pin-compatible replacements from other manufacturers if the original part is discontinued.
