SY58600UMI TR

Overview

The SY58600UMI TR is a discontinued differential receiver and driver IC from the Precision Edge series, manufactured by Microchip Technology. It operates on a 2.5V ±5% or 3.3V ±10% supply within an industrial temperature range of -40°C to +85°C. The device supports data rates up to 10.7Gbps and clock frequencies up to 7GHz. It features ultra-low jitter performance with less than 1ps RMS random jitter and less than 10ps peak-to-peak deterministic jitter. The component utilizes an 8-pin MLF package.

Feature Summary

• Features a unique patent-pending input termination architecture that accepts DC-coupled and AC-coupled inputs without external level shifting or termination resistor networks.
• Provides internal 50Ω output source termination for CML outputs with typical 400mV swing.
• Guarantees fast rise and fall times of less than 60ps across the full operating temperature range.

Applications

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

Procurement Notes

Verify the obsolete status of this specific part number before procurement planning. Confirm if the lead manufacturer has transitioned to RoHS-compliant variants such as the SY58600UMG-TR. Ensure compatibility with existing PCB footprints and thermal management requirements for the MLF package when sourcing replacements.

Selection Notes

Select this component for high-speed differential signal buffering where low jitter and minimal propagation delay are critical. Consider the SY58601U or SY58602U if 800mV LVPECL outputs are required instead of the standard CML outputs. Evaluate the need for Pb-free packaging options available in newer revisions of the product line.

Part Context

This device belongs to Micrel's Precision Edge product line, now under Microchip Technology. It is designed for high-performance networking and telecommunications applications requiring precise timing and signal integrity. The MLF package offers a compact footprint suitable for dense circuit board layouts.

Replacement Considerations

SY58600UMG-TR is listed as a direct replacement.
