SY100E111JI

Clock Buffers, Drivers Overview

The SY100E111JI is a low skew 1-to-9 differential clock driver manufactured by Microchip Technology. It operates within an extended VEE range of –4.2V to –5.5V and accepts one differential or single-ended input, fanning out the signal to nine identical differential outputs. The device includes an enable input that disables outputs when logic HIGH. It features guaranteed skew limits, internal 75KΩ input pulldown resistors, and a dedicated VBB output for single-ended reference voltage. The component is housed in a 28-pin PLCC package.

Clock Buffers, Drivers Feature Summary

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

Clock Buffers, Drivers Applications

• Clock distribution in high-performance ECL systems
• Signal buffering for differential logic interfaces
• System timing synchronization requiring low skew

Clock Buffers, Drivers Procurement Notes

Verify component authenticity through authorized channels as this part may be obsolete. Confirm RoHS compliance status, noting that Pb-Free variants exist with specific ordering suffixes. Ensure supply chain stability due to potential discontinuation status.

Clock Buffers, Drivers Selection Notes

Select the SY100E111JI for applications requiring precise timing alignment across multiple outputs. Ensure proper termination of all differential pairs into 50Ω loads to maintain specified skew performance. Verify compatibility with existing 10KH/100K I/O levels if interfacing with legacy components.
