SY58601UMI-TR

Overview

The SY58601UMI-TR is a precision, high-speed differential receiver manufactured by Microchip Technology. It supports data rates up to 5Gbps and clock frequencies up to 5GHz. The device features an ultra-low-jitter design with less than 1ps RMS random jitter and less than 10ps peak-to-peak deterministic jitter. It accepts minimum input swings of 200mV and provides typical 800mV LVPECL outputs. Operating from a 2.5V ±5% or 3.3V ±10% supply, it functions within the -40°C to +85°C industrial temperature range and is housed in an 8-pin MLF package.

Feature Summary

• Ultra-low-jitter architecture ensuring signal integrity for high-frequency applications
• Unique patent-pending input termination accepting AC-coupled and DC-coupled signals without external level shifting
• Guaranteed AC performance over the full industrial temperature range and voltage variations
• Internal 50Ω termination on differential inputs simplifying interface circuitry

Applications

• Backplane buffering
• OC-12 to OC-192 SONET/SDN clock and data distribution
• All Gigabit Ethernet distribution
• Fibre Channel distribution

Procurement Notes

Verify that the specific ordering suffix matches the required lead finish, as the 'I' suffix indicates Pb-Free NiPdAu plating while other variants may use Sn-Pb. Confirm the package type corresponds to the 8-pin MLF configuration. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the datasheet revision to confirm electrical characteristics remain consistent with your design specifications.

Selection Notes

Select this component when interfacing with CML, PECL, or LVDS sources requiring minimal external termination. It is suitable for designs needing high-speed buffering with strict jitter constraints. Consider alternative models like the SY58600U if CML outputs are preferred, or the SY58602U for lower 400mV LVPECL swing requirements. Evaluate power supply stability to maintain performance within the specified voltage tolerances.

Part Context

This device belongs to Micrel’s Precision Edge product line, now part of Microchip Technology. It is designed for high-speed digital communication systems requiring precise timing and signal conditioning. The SY58601U serves as a critical interface buffer between different logic families and high-speed transmission lines.

Replacement Considerations

For CML output requirements, consider the SY58600U. For 400mV LVPECL outputs, the SY58602U is a compatible alternative. Verify pin compatibility and electrical specifications before substituting any other devices in the SY5860x series.
