BCM56300B1KEBLG

Overview

The Broadcom BCM56300B1KEBLG is a high-performance, single-chip Ethernet switch designed for data center and enterprise core routing applications. It features the Trident II architecture, supporting line-rate forwarding of packets up to 256 bytes at 40 Gbps per port. The device integrates 48 ports of 10 Gigabit Ethernet and four ports of 40 Gigabit Ethernet, providing a total switching capacity of 2.56 Tbps. It supports advanced Quality of Service (QoS) features, including hardware-based traffic classification and scheduling, ensuring deterministic latency for real-time applications. The chip also incorporates comprehensive security features such as ACLs and encryption support.

Feature Summary

• Supports wire-speed packet processing with low latency for high-density 10G and 40G connectivity
• Integrates advanced QoS mechanisms for traffic prioritization and congestion management
• Provides robust security through extensive Access Control Lists and header manipulation capabilities

Applications

• Data center spine and leaf switches requiring high throughput
• Enterprise core routers demanding scalable Layer 3 forwarding
• Service provider edge aggregation platforms

Procurement Notes

Verify the specific suffix 'B1KEBLG' against the official Broadcom datasheet to confirm package type, temperature range, and lead-free status. Ensure compatibility with existing PCB footprints and thermal design specifications before procurement. Request RoHS compliance documentation from authorized distributors.

Selection Notes

Select this component when deploying high-port-count 10G/40G Ethernet environments requiring non-blocking switching fabric. Evaluate power consumption constraints as high-density switching generates significant heat. Compare against newer Trident III or IV series if future scalability beyond 2.56 Tbps is required.

Part Context

This part belongs to the Broadcom Trident II family of Ethernet switch processors. It is engineered for network infrastructure equipment manufacturers building next-generation switching platforms. The component serves as the central forwarding engine in modern data center architectures.

Replacement Considerations

Direct pin-to-pin replacements are limited due to proprietary packaging. Consider Broadcom's subsequent generations like the BCM569xx series for architectural upgrades, but verify software driver compatibility and board redesign requirements.
