SY58036UMI-TR

Clock Buffers, Drivers Overview

The SY58036UMI-TR is a high-speed, precision fanout buffer manufactured by Microchip Technology (originally Micrel). It provides six ultra-low skew LVPECL output copies of a selected differential input signal. The device integrates a 2:1 multiplexer for redundant clock switchover applications and features unique internal termination architecture supporting AC- or DC-coupled inputs such as CML, PECL, and LVDS. Operating on 2.5V or 3.3V supplies, it supports clock frequencies up to 7 GHz with propagation delays under 300 ps, rise/fall times under 80 ps, and output-to-output skew less than 20 ps.

Clock Buffers, Drivers Feature Summary

• Six-channel 400mV LVPECL fanout buffer with integrated 2:1 MUX input
• Ultra-low jitter design with typical RMS phase jitter of 50 fs
• Unique 3-pin input termination accepts signals as small as 100 mV without external networks
• Guaranteed performance over temperature and voltage with <20 ps output-to-output skew

Clock Buffers, Drivers Applications

• Redundant clock distribution systems
• SONET/SDH clock distribution
• Fibre Channel distribution
• Gigabit Ethernet clock distribution

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'TR' corresponds to the Tape and Reel packaging format specified in the datasheet. Confirm that the component is sourced from authorized channels to ensure authenticity, as the part was originally manufactured by Micrel before its acquisition by Microchip Technology. Check for Pb-Free bar-line indicators if RoHS compliance is required for new designs.

Clock Buffers, Drivers Selection Notes

Select this component when a 1:6 fanout buffer with low skew and integrated redundancy switching is required. It is suitable for interfaces requiring 400mV LVPECL outputs. For applications needing CML outputs, consider the SY58034U; for 800mV LVPECL outputs, consider the SY58035U. Ensure the PCB layout accommodates the 32-pin MLF package and connects the exposed pad to ground for thermal management.

Clock Buffers, Drivers Part Context

The SY58036U belongs to Micrel’s Precision Edge product line, designed for high-speed clock distribution. It is part of a family that includes the SY58034U (CML) and SY58035U (800mV LVPECL). The device utilizes Micrel's proprietary input isolation design to minimize crosstalk and features temperature-compensated LVPECL outputs compatible with 100K standards.
