SY100E111JY-TR

Clock Buffers, Drivers Overview

The SY100E111JY-TR is a low skew 1-to-9 differential clock driver with an enable input, designed for high-performance ECL systems. It accepts one differential or single-ended input and fans out the signal to nine identical differential outputs. The device features guaranteed skew limits, an extended VEE range of –4.2V to –5.5V, and internal 75KΩ input pulldown resistors. It operates within the industrial temperature range and is housed in a 28-pin PLCC package.

Clock Buffers, Drivers Feature Summary

• Low skew design with guaranteed within-device skew limits
• 1:9 differential fan-out with dedicated enable input
• Extended 100E VEE operating range from –4.2V to –5.5V
• Includes VBB output reference voltage for single-ended reception

Clock Buffers, Drivers Applications

• Clock distribution in high-performance ECL systems
• Differential clock buffering and driving
• Signal fan-out for multiple receiver inputs

Clock Buffers, Drivers Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to obsolescence. Confirm that the specific JY suffix corresponds to the Pb-free industrial variant with matte tin finish. Ensure supply chain stability due to potential discontinuation status associated with legacy ECL logic families.

Clock Buffers, Drivers Selection Notes

Select this component when low skew is critical for timing integrity across multiple loads. Verify compatibility with existing 100E I/O levels and ensure power supplies support the –4.2V to –5.5V VEE range. Confirm that the 28-pin PLCC package fits the PCB footprint requirements and that thermal management supports the industrial temperature range.

Clock Buffers, Drivers Part Context

This part belongs to the Micrel (now Microchip) SY10/100E111 series of low skew differential drivers. It is fully compatible with industry standard 10KH and 100K I/O levels and serves as a direct replacement for devices like the MC10E/100E111. The JY-TR designation indicates a tape and reel packaging format for the Pb-free industrial grade version.
