BCM53288MKPBG

Overview

The BCM53288MKPBG is an Ethernet IC from the Broadcom BCM5328x series, designed for high-performance networking applications. It integrates 24 Fast Ethernet (FE) PHY ports and two Gigabit Ethernet (GE) SGMII interfaces. Additionally, it features a 2.5 Gigabit Ethernet port and an IMP interface supporting MII or RvMII modes. The component is manufactured by Broadcom Limited and falls under the Communication & Networking ICs subcategory. It utilizes a Tray package format and is RoHS compliant. This device serves as a comprehensive solution for managing mixed-speed Ethernet connections within network infrastructure.

Feature Summary

• Integrates 24 Fast Ethernet PHY ports alongside dedicated Gigabit Ethernet SGMII interfaces for flexible connectivity.
• Supports 2.5 Gigabit Ethernet operation to accommodate emerging higher-speed network requirements.
• Includes an IMP interface compatible with both MII and RvMII protocols for processor integration.

Applications

• Enterprise network switches requiring mixed Fast Ethernet and Gigabit uplinks
• Industrial communication systems utilizing SGMII backplane connections
• Network infrastructure equipment needing 2.5G port support

Procurement Notes

Verify the specific ordering suffix and package variant against the manufacturer's official datasheet before procurement. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure compatibility with existing PCB footprints and thermal management solutions. Cross-reference the part number with authorized distributors to confirm current availability and authenticity.

Selection Notes

Select this component when a design requires a high density of 10/100 Mbps ports combined with multiple Gigabit uplinks. The inclusion of a 2.5G port makes it suitable for next-generation network upgrades. Consider the IMP interface options if direct connection to a host processor via MII or RvMII is necessary. Evaluate power consumption and thermal dissipation capabilities relative to the total port count in the final application.

Part Context

This part belongs to the Broadcom BCM5328x family of Ethernet controllers. Similar models in this series include the BCM53282 and BCM53283, which offer varying port configurations. These devices are commonly used in managed and unmanaged switch designs. The BCM53288MKPBG specifically targets applications needing a balance of legacy FE support and modern GE/2.5G connectivity.

Replacement Considerations

Check for direct substitutes within the BCM5328x series such as BCM53282SKPBG or BCM53283MKPBG. Verify pin-to-pin compatibility and software register mapping before substitution. Ensure that the alternative part supports the required 2.5G and SGMII interfaces. Consult Broadcom documentation for any functional differences between variants.
