SY10E111JY

Clock Buffers, Drivers Overview

The SY10E111JY 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 forces all Q outputs LOW when logic HIGH. Key electrical parameters include a maximum propagation delay of 630 ps for differential inputs and a guaranteed within-device skew of 50 ps. It is housed in a 28-pin PLCC package.

Clock Buffers, Drivers Feature Summary

• Low skew design with guaranteed within-device skew limits of 50 ps maximum
• Extended 100E VEE operating range from –4.2V to –5.5V
• Features an enable input (/EN) to disable outputs
• Includes internal 75KΩ input pulldown resistors

Clock Buffers, Drivers Applications

• Clock distribution in high-performance ECL systems
• Differential fan-out buffering for timing signals
• Single-ended reception using VBB reference voltage

Clock Buffers, Drivers Procurement Notes

Verify component authenticity through authorized channels as this part may be obsolete. Confirm lead finish specifications; the JY suffix indicates a Pb-Free matte-Sn finish. Check current availability status as the datasheet notes it is not recommended for new designs.

Clock Buffers, Drivers Selection Notes

Ensure both sides of the differential output are terminated into 50 Ω loads to maintain minimum skew specifications. Verify compatibility with industry standard 10KH and 100K I/O levels if interfacing with legacy components. Consider the SY100E111 variant for specific voltage level requirements.

Clock Buffers, Drivers Part Context

This component belongs to the ECLinPS™ family of logic devices. It shares common processing with other members of the series, allowing for tighter control of parameters like propagation delay through wafer characterization at the point of device personalization.
