SY100E111LEJI

Clock Buffers, Drivers Overview

The SY100E111LEJI is a low skew 1-to-9 differential clock driver manufactured by Microchip Technology in a 28-pin PLCC package. It supports both 5V and 3.3V power supply options, accepting one signal input that fans out to nine identical differential outputs. The device includes an enable input to control output states and features voltage and temperature compensated outputs with 75KΩ input pulldown resistors. Key performance metrics include a maximum toggle frequency of 800 MHz, part-to-part skew of 200ps, and within-device skew of 50ps.

Clock Buffers, Drivers Feature Summary

• Low skew design with 200ps part-to-part skew and 50ps output-to-output skew
• Supports 5V and 3.3V power supply options for ECL and PECL applications
• Includes an enable input to disable the device by forcing Q outputs LOW and Q outputs HIGH
• Features voltage and temperature compensated outputs with internal 75KΩ input pulldown resistors

Clock Buffers, Drivers Applications

• Clock distribution in high-performance systems
• Backplane or board-level clock distribution in +5V/+3.3V environments
• Systems requiring low jitter and precise timing synchronization

Clock Buffers, Drivers Procurement Notes

Verify component authenticity through authorized distributors. Confirm RoHS compliance status as Pb-Free packages are recommended for new designs. Check lead finish specifications (Sn-Pb vs Matte-Sn) based on ordering suffix. Ensure proper handling due to moisture sensitivity classification.

Clock Buffers, Drivers Selection Notes

Select this component when low skew clock distribution is required across multiple loads. Choose between AE and LE variants based on specific voltage requirements and availability. Consider the JY or JZ suffixes for Pb-free packaging needs. Verify termination requirements for unused differential pairs to maintain specified skew margins.

Clock Buffers, Drivers Part Context

This device belongs to the Precision Edge series from Micrel, now part of Microchip Technology. It is functionally similar to the SY10/100E111 but offers improved low jitter performance and low voltage operation capabilities. The LE variant specifically supports lower voltage operation compared to standard ECL devices.

Clock Buffers, Drivers Replacement Considerations

The SY100E111AEJI is a compatible alternative within the same family. Both devices share similar functionality and pinout configurations. Verify electrical characteristics match application requirements before substitution.
