SY58606UMG-TR

Clock Buffers, Drivers Overview

The SY58606UMG-TR is a high-speed, fully differential 1:2 CML fanout buffer manufactured by Microchip Technology. It operates from a 2.5V ±5% or 3.3V ±10% supply voltage and supports data throughput up to 4.25 Gbps. The device features guaranteed AC performance with propagation delays under 320 ps and within-device skew below 15 ps. It includes fail-safe input circuitry to prevent output oscillation during invalid input states and exhibits typical additive jitter of 100 fsRMS. The component is housed in a 16-lead QFN package and functions within an industrial temperature range of –40°C to +85°C.

Clock Buffers, Drivers Feature Summary

• Precision 1:2 CML Fanout Buffer with <15 ps within-device skew

• SONET Clock and Data Distribution
• Fibre Channel Clock and Data Distribution
• Gigabit Ethernet Clock And Data Distribution

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'TR' indicates a tape and reel quantity of 1,000 units. Confirm the package type is the 16-lead QFN (3 mm x 3 mm). Ensure the specific voltage variant 'U' matches the system's 2.5V or 3.3V power requirements. Check for moisture sensitivity handling instructions as indicated in the datasheet.

Clock Buffers, Drivers Selection Notes

Select this component for applications requiring low-skew clock distribution with CML outputs. It is suitable for interfacing with LVPECL, LVDS, or CML sources without external level shifting. Consider alternative models like the SY58607U or SY58608U if LVPECL or LVDS output swings are required instead of CML.

Clock Buffers, Drivers Part Context

The SY58606UMG-TR belongs to Microchip’s Precision Edge® product line of high-speed logic ICs. It is part of the SY58606U series, which includes variants with different packaging or output configurations. The '-TR' suffix specifically denotes the reel packaging format used for automated assembly processes.

Clock Buffers, Drivers Replacement Considerations

For LVPECL outputs, consider the SY58607U. For LVDS outputs, consider the SY58608U. These devices share similar input architectures but provide different output voltage swings.
