SY10EP11UKI-TR

Clock Buffers, Drivers Overview

The SY10EP11UKI-TR is a precision, high-speed 1:2 differential fanout buffer from the ECL Pro family. It supports PECL, LVPECL, ECL, and LVECL signaling standards with power supply options of 2.5V, 3.3V, or 5V. The device operates within an industrial temperature range of –40°C to +85°C and is housed in an 8-pin MSOP package. Key AC parameters include a maximum toggle frequency exceeding 3.0GHz, output-to-output skew under 20ps, and propagation delay under 300ps.

Clock Buffers, Drivers Procurement Notes

Verify that the ordering suffix 'KI' corresponds to the Industrial temperature range (-40°C to +85°C) and the K8-1 8-pin MSOP package as specified in the datasheet. Confirm the 'TR' suffix indicates Tape and Reel packaging. Ensure compatibility with the required logic family (PECL/LVPECL/ECL/LVECL) and voltage levels before procurement.

Clock Buffers, Drivers Selection Notes

Select this component when a 1:2 differential fanout buffer with guaranteed sub-20ps skew and >3GHz operation is required. The UKI variant is suitable for industrial environments. For lead-free requirements, consider the UKG suffix variants which utilize NiPdAu finishes. Ensure termination resistors are placed close to destination inputs to maintain signal integrity.

Clock Buffers, Drivers Part Context

The SY10EP11U series includes commercial (C) and industrial (I) temperature grades, available in both SOIC (Z) and MSOP (K) packages. The SY10EP11UKI-TR specifically denotes the Industrial grade MSOP version in tape and reel format. Cross-reference models include MC10EP11D/DT from Micrel/ON Semiconductor.

Clock Buffers, Drivers Replacement Considerations

Public confirmed substitute part numbers include MC10EP11D and MC10EP11DT. Verify pinout compatibility and electrical specifications against the original design requirements before substitution.

Clock Buffers, Drivers FAQ

What happens if the differential inputs are left open?

The differential inputs employ clamping circuitry to maintain stability. If the inputs are left open, the Q outputs will go LOW.

What is the maximum toggle frequency of the SY10EP11U?

The maximum toggle frequency (fMAX) is guaranteed to be greater than 3.0GHz across the operating temperature range.

How should the VEE pin be connected for PECL operation?

For PECL operation, the VEE pin should be connected to GND.
