BCM53154MB1ILFBG

Overview

The BCM53154MB1ILFBG is an Ethernet IC from Broadcom Limited, classified under Ethernet Switches. It features a RoboSwitch architecture with five integrated transceivers. The device supports data rates of 10 Mb/s, 100 Mb/s, 1 Gb/s, and 2.5 Gb/s, adhering to 10/100/1GBASE-T standards. It is housed in an FBGA-425 package for SMD/SMT installation. The component operates within a temperature range of -40°C to +85°C (Industrial Temperature).

Feature Summary

• Integrates four Gigabit Ethernet ports and one 2.5 Gigabit Ethernet port.
• Utilizes Broadcom RoboSwitch technology for efficient packet processing.
• Supports industrial operating temperatures for robust environmental performance.

Applications

• Enterprise network infrastructure switches
• Industrial automation networking equipment
• High-performance access points

Procurement Notes

Verify the specific suffix ILFBG against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Ensure the supplier provides valid traceability documentation. Confirm RoHS compliance status as required by project regulations before finalizing procurement orders.

Selection Notes

Select this component when a solution requiring mixed-speed ports (1G and 2.5G) is necessary. The industrial temperature rating makes it suitable for harsh environments where standard commercial grade parts may fail. Verify that the FBGA-425 footprint fits the target PCB layout constraints.

Part Context

This part belongs to the Broadcom BCM531xx series of Ethernet switches. These chips are designed for high-density switching applications. The MB1ILFBG designation indicates specific packaging and temperature grading variations within the broader product family.

Replacement Considerations

Check for direct substitutes within the BCM53154 series with different suffixes for varying temperature ranges or packages. Cross-reference with BCM53156XMB1KFBG if higher port counts are acceptable.
