BCM53107MIMMLG

Overview

The BCM53107MIMMLG is a seven-port Fast Ethernet switch integrated circuit manufactured by Broadcom Limited. It integrates seven 10/100 Mbps MACs and PHYs with an internal switching fabric, eliminating the need for external PHY components. The device supports IEEE 802.3x flow control and half-duplex backpressure mechanisms to manage network congestion. It includes hardware-based QoS features such as port-based priority queuing and bandwidth limiting to prioritize critical traffic. The component operates within a standard industrial temperature range and utilizes a lead-free package compliant with RoHS directives.

Feature Summary

• Integrates seven Fast Ethernet ports with combined MAC and PHY functionality on a single chip
• Supports IEEE 802.3x flow control and backpressure for effective data collision management
• Provides hardware-accelerated Quality of Service (QoS) for traffic prioritization
• Features built-in diagnostic capabilities including cable fault detection and link status monitoring

Applications

• Industrial automation controllers requiring multiple isolated Ethernet connections
• Smart home gateways and multimedia distribution hubs
• Embedded networking equipment and small form-factor routers
• Medical imaging devices with integrated network interfaces

Procurement Notes

Verify the specific suffix MIMMLG against official datasheets to confirm package type and temperature rating. Ensure supply chain partners provide valid traceability documentation. Check for moisture sensitivity levels prior to soldering. Confirm end-of-life status or obsolescence notices from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a design requires multiple independent Fast Ethernet interfaces without external PHYs. Compare pin compatibility with other BCM531xx series variants if space constraints exist. Verify that the required switching capacity meets the aggregate throughput needs of the target application. Consider thermal dissipation requirements associated with the specific package style used in the enclosure.

Part Context

This part belongs to the Broadcom BCM531xx family of Ethernet switches, designed for cost-effective multi-port connectivity solutions. It serves as a successor to earlier single-port or dual-port PHY/MAC combinations by consolidating functions. The series is widely utilized in embedded systems where board space and bill-of-materials costs are critical factors for mass production.

Replacement Considerations

Direct replacements include other BCM53107 variants with different suffixes indicating package or temperature changes. Cross-reference with BCM53125 series for higher port counts if expansion is needed. Verify pin-to-pin compatibility before substituting to avoid PCB redesign efforts.
