SY10EP11UKC

Clock Buffers, Drivers Overview

The SY10EP11UKC is a precision, high-speed 1:2 differential fanout buffer from the ECL Pro family. It supports 2.5V, 3.3V, and 5V power supplies for PECL, LVPECL, ECL, and LVECL operation. The device guarantees AC performance with fMAX > 3.0GHz, output-to-output skew < 20ps, propagation delay < 300ps, and transition times < 200ps. It features internal clamping circuitry to maintain stability under open input conditions, defaulting outputs LOW if inputs are floating. Operating temperature range is –40°C to +85°C in an 8-pin MSOP package.

Clock Buffers, Drivers Feature Summary

• Supports 2.5V, 3.3V, and 5V supply voltages for PECL/LVPECL/ECL/LVECL compatibility
• Guaranteed AC parameters including fMAX > 3.0GHz and within-device skew < 20ps
• Internal clamping circuitry prevents instability when differential inputs are left open
• Available in 8-pin MSOP (K8-1) commercial grade package

Clock Buffers, Drivers Applications

• High-speed clock distribution networks requiring low skew
• Differential signal buffering in telecommunications equipment
• Data acquisition systems utilizing PECL or ECL interfaces
• Test and measurement instruments requiring precise timing alignment

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'KC' corresponds to the K8-1 8-pin MSOP package with commercial operating temperature range (-40°C to +85°C). Confirm lead finish is Sn-Pb as specified in the datasheet table. Ensure the specific variant matches the required voltage domain and package type for the target design.

Clock Buffers, Drivers Selection Notes

Select this component when low output-to-output skew (< 20ps) and high toggle frequency (> 3.0GHz) are critical. Compare against SY100EP11UKC if higher drive current or different DC characteristics are needed. Ensure termination resistors match the selected VCC level (2.5V, 3.3V, or 5V) to maintain signal integrity and proper biasing.

Clock Buffers, Drivers Part Context

This part is part of the Micrel SY10/100EP11U series, which serves as a successor to older devices like the EL11V with improved AC performance. The SY10EP11U variant typically denotes specific DC electrical characteristics compared to the SY100EP11U. Cross-reference tables indicate equivalents such as ON Semiconductor MC10EP11D/DT.

Clock Buffers, Drivers Replacement Considerations

Public confirmed substitutes include ON Semiconductor MC10EP11D and MC10EP11DT. Verify pinout compatibility and electrical specifications against the original requirements before substitution.
