SY100EP111UTG-TR

Clock Buffers, Drivers Overview

The SY100EP111UTG-TR is a high-speed, low skew 1-to-10 differential fanout buffer designed for clock distribution in high-performance systems. It supports 2.5V and 3.3V power supply options and features an internal 2:1 multiplexer to select between two differential clock sources (CLK0 or CLK1). The device guarantees AC parameters including fMAX of 3GHz, output-to-output skew under 25ps, and propagation delay under 400ps across the industrial temperature range of –40°C to +85°C. It operates with LVPECL, LVECL, and HSTL logic levels and is housed in a 32-pin TQFP package.

Clock Buffers, Drivers Feature Summary

• Internal 2:1 multiplexer allows selection between two differential clock inputs
• Guaranteed maximum frequency of 3GHz with less than 25ps output-to-output skew
• Supports LVPECL, LVECL, and HSTL input/output standards
• Includes VBB reference voltage output for single-ended input applications

Clock Buffers, Drivers Applications

• Clock distribution in high-performance digital systems
• Fanout buffering for LVPECL/LVECL/HSTL interfaces
• High-speed data acquisition and communication equipment

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 'G' suffix indicates the lead-free NiPdAu finish variant. Ensure the component meets the required industrial operating temperature range of –40°C to +85°C for the specific application environment.

Clock Buffers, Drivers Selection Notes

Select this component when a 1-to-10 differential fanout buffer with low skew is required. The internal multiplexer simplifies design by allowing direct selection between two clock sources without external switching logic. Ensure the system power supply aligns with either the 2.5V or 3.3V LVPECL configuration and that termination resistors are placed close to destination inputs to maintain signal integrity.

Clock Buffers, Drivers Part Context

This part belongs to the Precision Edge SY100EP series of high-speed clock drivers manufactured by Micrel, now part of Microchip Technology. The 'UTG' designation identifies the 32-pin TQFP package with lead-free finish, while 'TR' denotes the tape and reel shipping method. It is functionally equivalent to the non-reel version SY100EP111UTG.

Clock Buffers, Drivers Replacement Considerations

Publicly confirmed substitute part numbers include SY100EP111UTI and SY100EP111UTG. These variants share identical electrical specifications and pinouts but differ in packaging type (tube vs. tape and reel) or lead finish composition.
