• Integrates hardware-accelerated security and encryption engines
• Provides comprehensive QoS scheduling and traffic management capabilities

Applications

• Data center spine and leaf switches
• Service provider edge routers
• Core network aggregation platforms

Procurement Notes

Verify the specific suffix IPB against official Broadcom documentation to confirm package type and temperature range. Ensure compatibility with required external components such as DRAM and PHY devices before procurement. Request official datasheets and errata sheets to validate pin assignments and electrical characteristics for your specific design implementation.

Selection Notes

Select this component when designing systems requiring high port density and advanced traffic engineering. Evaluate power consumption requirements against available cooling solutions. Confirm that the host processor can manage the control plane interfaces provided by the silicon. Consider future scalability needs regarding port speeds and buffer sizes.

Part Context

This part is part of the Trident II series, which succeeded earlier generations like the Trident chip. It represents a significant step in integrating switching, routing, and security functions into a single silicon die. The family is widely used in enterprise and carrier-grade infrastructure due to its reliability and feature set.

Replacement Considerations

Direct replacements may include other Broadcom Trident series chips such as the BCM56840 or BCM56960 depending on port count and speed requirements. Verify pin-to-pin compatibility and software driver support before substituting. Consult Broadcom for current lifecycle status and recommended alternatives.
