SY10EL11VZG-TR

Clock Buffers, Drivers Overview

The SY10EL11VZG-TR is a 1:2 differential fanout buffer from the Precision Edge® series, designed for high-speed AC performance. It supports 3.3V and 5V power supplies with a typical propagation delay of 265ps at +85°C and within-device skew of 5ps. The device features internal 75KΩ input pull-down resistors and clamping circuitry to maintain stability under open input conditions. Packaged in an 8-pin SOIC (Z8-1) tube, it operates over an industrial temperature range of -40°C to +85°C.

Clock Buffers, Drivers Feature Summary

• 1:2 Differential Fanout Buffer with 265ps typical propagation delay
• 5ps within-device skew between outputs
• Internal 75KΩ input pull-down resistors
• Clamping circuitry for open input stability

Clock Buffers, Drivers Applications

• High-performance clock distribution networks
• Differential signal buffering in telecommunications equipment
• Data acquisition systems requiring low skew

Clock Buffers, Drivers Procurement Notes

Verify that the ordering suffix 'TR' corresponds to the Tape and Reel packaging format as specified in the manufacturer's documentation. Confirm the 'ZG' suffix indicates the Pb-Free package variant with NiPdAu lead finish intended for industrial temperature operation (-40°C to +85°C). Ensure compatibility with existing PCB footprints for the 8-pin SOIC (Z8-1) package.

Clock Buffers, Drivers Selection Notes

Select this component when low propagation delay and minimal skew are critical for timing integrity. The device replaces older SY10/100EL11 models with improved output waveform characteristics. Consider the internal pull-down resistors if input termination strategies need simplification. Verify that the 150mV minimum input swing requirement aligns with the source driver capabilities.

Clock Buffers, Drivers Part Context

This part belongs to the SY10EL11V family of differential fanout buffers manufactured by Micrel, Inc., now part of Microchip Technology. The SY10EL11VZG-TR specifically denotes the industrial grade, Pb-free version supplied in tape and reel packaging. It serves as a functional upgrade to legacy ECL/LVPECL buffers like the E111A/L.

Clock Buffers, Drivers Replacement Considerations

The datasheet explicitly states that this device replaces the SY10/100EL11 series. Designers upgrading from these legacy parts should verify that the improved transition times and internal pull-down resistors do not conflict with existing circuit termination requirements.
