SY58012UMI-TR

Clock Buffers, Drivers Overview

The SY58012UMI-TR is a precision, high-speed, fully differential 1:2 LVPECL fanout buffer manufactured by Microchip Technology. It operates from a 2.5V ±5% or 3.3V ±10% power supply and supports clock signals up to 5 GHz or data rates of 5 Gbps. The device features guaranteed AC performance with propagation delays under 260 ps, rise/fall times below 110 ps, and maximum skew of 15 ps. It incorporates unique internal input termination that accepts differential inputs as low as 100 mV without external level-shifting networks. The component is housed in a 16-pin QFN package and functions within an industrial temperature range of –40°C to +85°C.

Clock Buffers, Drivers Feature Summary

• Precision 1:2 LVPECL fanout buffer with 800 mV output swing
• Internal 3-pin input termination architecture for LVPECL, LVDS, and CML compatibility
• Low jitter design with 60 fs RMS phase jitter
• High-speed operation supporting 5 GHz clocks and 5 Gbps data

Clock Buffers, Drivers Applications

• SONET and GigE clock distribution
• Fibre Channel clock and data distribution
• Backplane distribution
• Multiprocessor synchronous clock distribution

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'TR' corresponds to the Tape and Reel packaging configuration containing 1,000 units per reel. Confirm the 'MI' designation aligns with the specified 3 mm x 3 mm QFN-16 package dimensions and lead-free material composition. Ensure the voltage suffix 'U' matches the required 2.5V/3.3V operating supply specifications.

Clock Buffers, Drivers Selection Notes

Select this component when a low-skew, high-speed fanout buffer is required for LVPECL signal distribution. It is suitable for applications needing interface flexibility with LVDS or CML sources via its internal termination. Consider alternative models like the SY58013U if a lower 400 mV output swing is acceptable, or the SY58011U if CML outputs are preferred over LVPECL.

Clock Buffers, Drivers Part Context

The SY58012U belongs to Microchip’s Precision Edge® product line of high-speed logic devices. This specific part number variant utilizes the 'TR' suffix to denote tape and reel packaging, distinguishing it from tube-packaged versions such as the SY58012UMG. It serves as a critical component for maintaining signal integrity in high-frequency digital systems.
