SY58011UMI-TR

Clock Buffers, Drivers Overview

The SY58011UMI-TR is a Precision Edge® 1:2 CML fanout buffer and translator manufactured by Microchip Technology. It operates on a single supply voltage ranging from 2.375V to 3.6V, supporting both 2.5V ±5% and 3.3V ±10% configurations. The device processes clock signals up to 7GHz or data patterns up to 10.7Gbps with a typical RMS phase jitter of 49fs (12kHz–20MHz). It features guaranteed AC performance including propagation delay under 250ps, rise/fall times under 60ps, and maximum skew of 15ps. The component accepts differential inputs as low as 100mV and provides two identical buffered output copies in a 16-pin QFN package.

Clock Buffers, Drivers Feature Summary

• Ultra-low jitter performance with 49fs RMS phase jitter (typical) at 622MHz
• High-speed operation supporting 7GHz clocks and 10.7Gbps NRZ data rates
• Unique 3-pin input termination architecture accepting LVPECL, LVDS, and CML signals without external level-shifting networks
• Low skew characteristics with channel-to-channel skew under 15ps and part-to-part skew under 100ps

Clock Buffers, Drivers Applications

• SONET and Gigabit Ethernet clock distribution
• Fibre Channel clock and data distribution
• Backplane signal routing
• Data distribution for OC-48, OC-48+FEC, and XAUI interfaces
• Multiprocessor synchronous clock distribution systems

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'TR' corresponds to tape and reel packaging when sourcing this component. Confirm that the specific variant matches the required industrial temperature range of –40°C to +85°C. Ensure the procurement documentation aligns with the manufacturer's specifications for the 16-pin QFN package and lead-free construction standards.

Clock Buffers, Drivers Selection Notes

Select the SY58011UMI-TR for applications requiring high-frequency CML buffering with minimal jitter. This component is suitable for designs needing compatibility with LVPECL, LVDS, or CML inputs directly. Consider alternative models like the SY58012U or SY58013U if LVPECL outputs are required instead of CML outputs. Ensure power supply decoupling meets the recommended 0.1μF and 0.01μF capacitor guidelines near VCC pins.

Clock Buffers, Drivers Part Context

The SY58011U belongs to Micrel’s Precision Edge® product line, which focuses on high-speed, low-jitter timing solutions. Following the acquisition of Micrel by Microchip Technology, these components are now distributed under the Microchip brand while retaining their original functional specifications and design heritage. The device is part of a family that includes related fanout buffers and translators designed for demanding telecommunications and networking applications.

Clock Buffers, Drivers Replacement Considerations

For direct replacements within the same family, consider the SY58011UMG or SY58011UMGTR variants, which share identical electrical characteristics but may differ in packaging details or manufacturing origin. Verify pin compatibility and thermal requirements when substituting.
