SY100EP14AUKG

Clock Buffers, Drivers Overview

The SY100EP14AUKG 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 MUX 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 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: >2GHz fMAX, <25ps within-device skew, <250ps tr/tf
• 2:1 Differential MUX input with patented isolation design to minimize crosstalk
• Flexible supply voltage operation: 2.5V/3.3V (LVPECL) or -2.37V/-3.6V (LVECL)
• Synchronous enable pin prevents runt clock pulses during state changes

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 (K4-20-1) and operating range is Industrial (-40°C to +85°C). Check lead finish specifications (NiPdAu Pb-free) against current manufacturing requirements.

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. Use VBB reference for single-ended or AC-coupled inputs. Terminate outputs with 50Ω to VCC-2V for proper signal integrity.

Clock Buffers, Drivers Part Context

This component belongs to Micrel’s high-speed clock synchronization family. It serves as a fanout buffer and clock driver. The device integrates a 2:1 MUX for input selection and a synchronous enable feature. It is designed for systems requiring precise clock distribution with minimal jitter and skew.
