SY100EP111UTI-TR

Clock Buffers, Drivers Overview

The SY100EP111UTI-TR is a high-speed, low-skew 1-to-10 differential fanout buffer manufactured by Microchip Technology. It operates on 2.5V or 3.3V power supplies and supports LVPECL, LVECL, and HSTL logic levels. The device features an internal 2:1 multiplexer for selecting between two differential clock sources (CLK0/CLK1). Key electrical parameters include a maximum frequency of 3GHz, within-device skew under 25ps, propagation delay up to 400ps, and output rise/fall times under 250ps. It is housed in a 32-pin TQFP package with tape-and-reel packaging.

Clock Buffers, Drivers Feature Summary

• 1-to-10 differential fanout buffer with internal 2:1 input multiplexer
• Guaranteed AC performance: fMAX = 3GHz, skew < 25ps, propagation delay < 400ps
• Supports 2.5V and 3.3V supply voltages with LVPECL/LVECL/HSTL compatibility
• Includes VBB reference voltage output for single-ended input applications

Clock Buffers, Drivers Applications

• Clock distribution in high-performance systems
• Low skew differential clock buffering
• Selecting between dual differential clock sources

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'TR' corresponds to the Tape and Reel packaging format as specified in the datasheet. Confirm that the component meets industrial temperature range requirements (-40°C to +85°C) for the intended application environment. Ensure proper decoupling capacitors are used for VCC and VBB pins during implementation.

Clock Buffers, Drivers Selection Notes

Select this component when a 1:10 fanout ratio with minimal skew is required. The internal 2:1 mux allows switching between two clock inputs without external logic. Verify that the system voltage aligns with the 2.5V or 3.3V operating ranges. Consider the 32-pin TQFP package size for PCB layout constraints.

Clock Buffers, Drivers Part Context

This part belongs to the Precision Edge® SY100EP111U series, designed for high-speed clock distribution. The 'UTI' designation indicates the Industrial temperature range and Sn-Pb lead finish, while '-TR' specifies the tape and reel packaging option. It is part of Micrel's (now Microchip) ECL Pro™ family of devices.

Clock Buffers, Drivers Replacement Considerations

Check for Pb-free alternatives such as SY100EP111UTG or SY100EP111UTGTR if RoHS compliance is required. Ensure pinout and electrical characteristics match exactly when substituting.
