The BCM56445B0IFSBLG is a Broadcom Ethernet switch integrated circuit designed for high-performance networking applications. It features a port configuration of 24 Gigabit Ethernet ports and four 10 Gigabit Ethernet ports, providing flexible connectivity options for enterprise and service provider networks. The component operates within the Switch ICs category and utilizes the IFSB package variant. This specific part number has been officially discontinued by the manufacturer.
This component is officially discontinued and no longer in active production. Verification of availability should focus on surplus or secondary market sources rather than direct manufacturer allocation. Buyers must confirm lot dates and authenticity through authorized distributors when sourcing end-of-life inventory. Compliance with RoHS standards is documented in official product specifications.
Engineers replacing this discontinued switch IC should evaluate current Broadcom portfolio members offering equivalent port densities and throughput capabilities. Selection criteria must prioritize interface compatibility and pin-out alignment to ensure seamless integration into existing designs without requiring major PCB revisions. Consulting the latest Broadcom datasheets is essential for identifying functional equivalents.
The BCM56445 series belongs to Broadcom's family of Ethernet switch solutions targeting high-density networking environments. These components support advanced packet processing required for modern data center and telecom architectures. The IFSB suffix indicates specific packaging and thermal characteristics distinct from other variants within the broader BCM5644x product line.
Official substitution requires consulting Broadcom's discontinuation notification documents for recommended next-generation parts. Potential replacements must match the 24GE + 4x10GE architecture while ensuring software compatibility with existing network operating systems.
