SY10E111JI

Clock Buffers, Drivers Overview

The SY10E111JI is a low skew 1-to-9 differential clock driver manufactured by Microchip Technology (originally Micrel). 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. Key electrical parameters include a propagation delay of 430–630 ps for differential inputs and a maximum within-device skew of 50 ps across all temperatures. It features a dedicated VBB output for single-ended reference voltage.

Clock Buffers, Drivers Feature Summary

• Low skew design with guaranteed limits of 50 ps maximum
• Extended power supply range: VEE from –4.2V to –5.5V
• Differential 1:9 fan-out with Enable control
• Compatible with industry standard 10KH/100K I/O levels

Clock Buffers, Drivers Applications

• Clock distribution in high-performance ECL systems
• High-speed digital signal processing interfaces
• Telecommunications equipment requiring precise timing

Clock Buffers, Drivers Procurement Notes

Verify component authenticity through authorized channels as this part may be obsolete. Check RoHS compliance status, noting that Pb-Free variants exist under different suffixes (JY). Confirm lead finish specifications (Sn-Pb vs Matte-Sn) against current environmental regulations before procurement.

Clock Buffers, Drivers Selection Notes

Select the SY10E111JI for applications requiring minimal interconnect skew and differential signaling. Ensure proper termination of all unused differential pairs into 50 Ω loads on the same package side to maintain specified skew performance. Verify compatibility with existing ECL power supplies (-5V nominal).

Clock Buffers, Drivers Part Context

This component belongs to the SY10/100E111 family of low skew clock drivers. It shares common processing with the ECLinPS™ family, allowing for tighter parameter control. The 'JI' suffix indicates the Industrial temperature range (-40°C to +85°C) and J28-1 PLCC package type.

Clock Buffers, Drivers Replacement Considerations

Publicly confirmed direct substitutes include the MC10E111 and MC100E111 from ON Semiconductor. These parts are fully compatible with industry standards and offer similar pinouts and electrical characteristics.
