BCM53108VIMLG

Overview

The BCM53108VIMLG is a nine-port Fast Ethernet switch integrated circuit manufactured by Broadcom Limited. It features five 10/100 Mbps PHY ports and four Gigabit Ethernet ports, supporting Energy Efficient Ethernet (EEE) for power reduction. The device integrates an ARM926EJ-S processor core to manage switching functions and includes hardware-based security features such as MAC address filtering and VLAN tagging. It operates within a commercial temperature range and utilizes a lead-free, RoHS-compliant package.

Feature Summary

• Integrates five Fast Ethernet and four Gigabit Ethernet physical layer transceivers
• Includes an embedded ARM926EJ-S processor for advanced switching control
• Supports Energy Efficient Ethernet standards to minimize power consumption during low traffic
• Provides hardware-accelerated security mechanisms including MAC filtering and VLAN support

Applications

• Residential gateway devices requiring multi-port connectivity
• Enterprise access points with mixed speed port requirements
• Industrial control systems needing reliable Ethernet switching
• Network infrastructure equipment utilizing EEE capabilities

Procurement Notes

Verify the specific suffix 'VIMLG' against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure compliance with RoHS directives and moisture sensitivity level classifications before integration into production assemblies. Cross-reference pinout diagrams with PCB layout specifications to prevent interface mismatches.

Selection Notes

Select this component when a solution combining Fast Ethernet and Gigabit ports is required within a single IC. Consider the integrated ARM processor if software-defined switching or complex packet processing is needed without external controllers. Evaluate power budgets carefully, noting that EEE support aids in meeting energy efficiency targets for always-on network nodes.

Part Context

This part belongs to Broadcom's portfolio of Ethernet switch controllers designed for high-performance networking applications. It addresses the need for consolidated switching solutions in environments where space constraints and power efficiency are critical. The inclusion of both FE and GE ports allows for flexible uplink and downlink configurations in modern network architectures.

Replacement Considerations

Consult official Broadcom documentation for direct cross-references. Verify compatibility with existing firmware and hardware designs before substituting with alternative Broadcom switch ICs or competitor products offering similar port counts.
