SY58032UMG-TR

Clock Buffers, Drivers Overview

The SY58032UMG-TR is a Precision Edge® ultra-high-speed 1:8 fanout buffer with LVPECL outputs and internal termination, manufactured by Microchip Technology. It operates from a 2.5V ±5% or 3.3V ±10% supply within an industrial temperature range of –40°C to +85°C. The device supports clock frequencies up to 4GHz, featuring propagation delays under 330ps, rise/fall times below 110ps, and output-to-output skew less than 20ps. Typical RMS phase jitter is 76fs at 622MHz. It accepts differential inputs as low as 100mV via a unique VT pin architecture for LVPECL, CML, and LVDS compatibility.

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'TR' corresponds to Tape and Reel packaging in official documentation. Confirm RoHS compliance status and moisture sensitivity level requirements before procurement. Ensure the specific package variant matches design constraints.

Clock Buffers, Drivers Selection Notes

Select this component for applications requiring high-speed 1:8 fanout buffering with LVPECL outputs. Consider the SY58031U or SY58033U if different output swing characteristics are needed. Ensure input signal levels meet the minimum 100mV requirement for proper operation.

Clock Buffers, Drivers Part Context

The SY58032U belongs to Micrel’s Precision Edge® product line, now part of Microchip Technology. It is designed for high-speed clock distribution networks where low jitter and precise timing are critical. The MLF-32 package provides thermal efficiency through its exposed pad design.

Clock Buffers, Drivers Replacement Considerations

Public confirmed substitute part numbers include SY58031U and SY58033U. Verify output voltage swing and interface compatibility before substitution.
