SY100E111LJG TR

Clock Buffers, Drivers Overview

The SY100E111LJG 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-PLCC surface-mount package with J-leads (11.48x11.48 mm). Designed for high-speed signal integrity, it supports operation across an industrial temperature range of -40°C to +85°C. This component belongs to the 100E series and is intended for applications requiring precise clock distribution with low skew characteristics.

Clock Buffers, Drivers Procurement Notes

Verify component authenticity through authorized channels as counterfeits exist. Confirm RoHS compliance status, as some variants may not meet current environmental standards. Check for moisture sensitivity handling requirements during storage and assembly. Ensure the specific suffix 'TR' matches reel packaging specifications if automated placement is required. Validate lead availability as production status may vary.

Clock Buffers, Drivers Selection Notes

Select this part when a single differential PECL source must drive nine identical loads without signal degradation. Ensure the system power supply remains stable between 3V and 5.5V. Verify that the PCB layout accommodates the 28-PLCC footprint dimensions. Consider thermal management capabilities if operating near the upper temperature limit of +85°C.

Clock Buffers, Drivers Part Context

This component is part of Microchip's Precision Edge 100E series, which focuses on high-performance clocking solutions. It serves as a buffer within logic IC families designed for ECL/PECL compatibility. The device replaces older discrete buffering solutions by integrating multiple output drivers into a single compact package, reducing board space and parasitic capacitance effects.

Clock Buffers, Drivers Replacement Considerations

The MC100LVE111FNG and MC100LVE111FNR2G from onsemi are listed as similar alternatives. Verify pin-to-pin compatibility and electrical parameter alignment before substitution. Confirm that the replacement devices support the same PECL voltage levels and load requirements.
