SY100EP14AUKG-TR

Clock Buffers, Drivers Overview

The SY100EP14AUKG-TR is a high-speed, 2 GHz differential PECL/ECL 1:5 fanout buffer optimized for ultra-low skew applications. It features a 2:1 differential input multiplexer and synchronous enable pin. The device operates with flexible supply voltages of 2.5V or 3.3V (LVPECL) and -2.37V to -3.6V (LVECL). Within-device skew is guaranteed to be less than 25ps over temperature and supply voltage. Propagation delay ranges from 300ps to 550ps, with rise/fall times under 250ps. It accepts LVPECL, LVECL, HSTL, and ECL logic inputs.

Clock Buffers, Drivers Feature Summary

• Guaranteed AC parameters including >2GHz fMAX, <25ps within-device skew, and <550ps propagation delay
• Integrated 2:1 differential input MUX with unique isolation design to minimize adjacent channel crosstalk
• Flexible supply voltage operation for 2.5V/3.3V systems and wide operating temperature range (-40°C to +85°C)
• Includes VBB reference for single-ended or AC-coupled PECL inputs and internal pull-down resistors

Clock Buffers, Drivers Applications

• SONET Clock and Data distribution
• Fibre Channel Clock and Data distribution
• Ethernet Clock and Data distribution

Clock Buffers, Drivers Procurement Notes

Verify the component status as Not Recommended for New Designs (NRND). Confirm package type is 20-Pin TSSOP and lead finish is NiPdAu Pb-free. Check for tape and reel packaging requirements if ordering the TR suffix variant.

Clock Buffers, Drivers Selection Notes

Select this part for redundant clock switchover applications requiring low skew. Ensure interface compatibility with LVPECL, LVECL, or HSTL signals. Terminate unused outputs with 50Ω to VCC-2V to balance the output. Use appropriate termination networks like Thevenin or Y-termination near destination inputs.
