Overview
The BCM53440B0IFSBG is a Layer 2+ managed switch IC manufactured by Broadcom Limited. It integrates twenty-four Gigabit Ethernet ports and four 10 Gigabit Ethernet uplink ports, providing high-density connectivity for enterprise access and aggregation layers. The device supports advanced switching features including VLAN tagging, Quality of Service (QoS) prioritization, Link Aggregation Control Protocol (LACP), Access Control Lists (ACLs), and IGMP Snooping for optimized multicast traffic management.
Feature Summary
- Integrates 24 Gigabit Ethernet ports alongside 4 dedicated 10 Gigabit Ethernet uplinks for scalable bandwidth expansion.
- Supports Layer 2+ managed switching capabilities with comprehensive security and traffic control protocols.
- Includes hardware-accelerated functions for VLAN segmentation, QoS classification, and link aggregation.
Applications
- Enterprise network access switches requiring high port density.
- Aggregation layer infrastructure in campus or data center environments.
- Managed switches supporting advanced L2+ routing and security policies.
Procurement Notes
Verify the specific ordering suffix to ensure compatibility with required package variants and temperature ranges. Confirm RoHS compliance status through official documentation before integration. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status.
Selection Notes
Select this component when designing switches that require a mix of standard Gigabit access ports and high-speed 10 Gigabit uplinks. Ensure the system design accommodates the thermal requirements of the BGA package. Evaluate power consumption profiles against available cooling solutions for the target enclosure form factor.
Part Context
This model belongs to the Broadcom BCM53xxx series of Ethernet switch controllers. These chips are widely utilized in networking equipment manufacturers' products to deliver robust switching performance. The BCM53440 variant specifically targets applications needing substantial port counts with mixed speed interfaces.
Replacement Considerations
Consult official Broadcom documentation for verified cross-references. Potential alternatives within the same family may include BCM53442A0KFSBG or BCM53457A0KFSBG, subject to pinout and feature compatibility verification.
