It belongs to the Trident II family, designed for data center and enterprise core switching applications. The device supports a switching capacity of 1.92 Tbps with a packet buffer of 3.75 Mbits. It features 24 ports of 10 Gigabit Ethernet and 4 ports supporting 1/10 Gigabit Ethernet speeds. The component utilizes a 65 nm process technology and is housed in a 28x28 mm BGA package with 1008 pins. It operates within a commercial temperature range of 0°C to 70°C ambient.

Drivers, Receivers, Transceivers Feature Summary

• Supports advanced Quality of Service (QoS) mechanisms including strict priority queuing and weighted round robin scheduling.
• Integrates hardware-based security features such as ACLs and MAC address filtering for network protection.
• Enables non-blocking wire-speed forwarding with low latency suitable for high-throughput environments.

Drivers, Receivers, Transceivers Applications

• Data center spine and leaf switches
• Enterprise core routing and switching
• Service provider edge aggregation

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'AIFSBLG' against the manufacturer's official datasheet to confirm pinout compatibility and thermal specifications. Ensure that the ordering information matches the exact package type and RoHS compliance status required for your design. Cross-reference the manufacturing date code to ensure availability aligns with production schedules.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing switches requiring 24 fixed 10GbE ports alongside uplink flexibility. Evaluate power consumption requirements against the typical operating current specified in the electrical characteristics section. Confirm that the PCB layout supports the dense BGA pitch and thermal dissipation needs for continuous operation at maximum throughput.

Drivers, Receivers, Transceivers Part Context

This part is part of Broadcom's Trident II series, which succeeded earlier generations like the Tomahawk predecessor in specific port density configurations. It competes with similar high-density switching ASICs from other semiconductor vendors targeting the same data center infrastructure market segment.

Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-to-pin replacements are rare due to proprietary architecture differences. Consider Broadcom's own next-generation Trident III or Tomahawk series for upgrades, though these typically require significant schematic and layout redesigns rather than simple substitution.
