SY100E111LJI-TR

Clock Buffers, Drivers Overview

The SY100E111LJI-TR is a Precision Edge clock fanout buffer manufactured by Microchip Technology. It features a single PECL input driving nine differential PECL outputs, providing a 1:9 distribution ratio. The device operates within a supply voltage range of 3V to 5.5V and is housed in a 28-pin PLCC package with J-leads. Designed for high-speed timing applications, it supports surface-mount installation and functions across an industrial temperature range of -40°C to +85°C.

• Telecommunications infrastructure equipment

Clock Buffers, Drivers Procurement Notes

Verify component status as the SY100E111LJI variant is listed as discontinued by major distributors. Confirm availability of the specific tape-and-reel suffix (-TR) against current stock levels. Ensure compliance with RoHS requirements, noting that some variants may not meet current environmental standards. Validate lead times and obsolescence notices before finalizing procurement plans.

Clock Buffers, Drivers Selection Notes

Select this component when a single-ended or differential PECL source must drive nine distinct loads without signal degradation. Ensure the design accommodates the 28-PLCC footprint and thermal characteristics. Verify that the system power supply remains stable between 3V and 5.5V to maintain specified electrical performance and timing parameters.

Clock Buffers, Drivers Part Context

This part belongs to the Microchip 100E Precision Edge series, which focuses on low-jitter clock buffering solutions. The SY100E111 family provides robust signal integrity for high-frequency applications. The LJI suffix specifically denotes the 28-pin PLCC package configuration with J-leads for surface mounting.

Clock Buffers, Drivers Replacement Considerations

Publicly documented substitutes include the MC100LVE111FNG and MC100LVE111FNR2G from onsemi. These alternatives offer similar 1:9 fanout capabilities but utilize LVPECL logic levels rather than standard PECL. Verify pin compatibility and voltage level shifts before implementing these replacements.
