GD82550EYSL4MJ

Controllers Overview

The Intel GD82550EYSL4MJ is a Gigabit Ethernet controller based on the 82550EB architecture, designed for high-performance server and workstation networking. It supports full-duplex operation at 10/100/1000 Mbps with integrated MAC and PHY functions. The component features advanced packet filtering, checksum offload capabilities, and support for VLAN tagging. It utilizes a PCI interface for system connectivity and includes hardware-based flow control to manage network congestion efficiently.

Controllers Feature Summary

• Integrated MAC and PHY for simplified board design
• Hardware acceleration for TCP/IP checksums and VLAN tagging
• Advanced packet filtering and multicast address handling
• Support for standard PCI bus interface

Controllers Applications

• Server mainboard networking solutions
• Workstation gigabit connectivity
• Network infrastructure equipment

Controllers Procurement Notes

Verify the specific revision level and packaging type against current datasheets, as legacy components may have limited availability or alternative pin-compatible variants. Confirm compatibility with existing BIOS and driver environments before integration into new designs.

Controllers Selection Notes

Select this component when a reliable, industry-standard Gigabit Ethernet solution with integrated PHY is required for PCI-based systems. Consider power consumption and thermal requirements relative to the host platform's cooling capabilities and form factor constraints.

Controllers Part Context

This part belongs to the Intel 8255x family of Fast Ethernet and Gigabit Ethernet controllers, widely used in enterprise computing during the early 2000s. It serves as a foundational networking component for platforms requiring robust, low-latency data transfer capabilities without external PHY dependencies.

Controllers Replacement Considerations

Direct replacements are limited due to age. Check for newer Intel 8257x series controllers if PCI Express interfaces are available, though pinouts and drivers will differ significantly. Verify mechanical fit and electrical compatibility carefully.
