The BCM56134B1IFSBLG is a six-port Gigabit Ethernet switch fabricated in a compact package to optimize printed circuit board layout. It supports 128 Compact Field Processor (CFP) entries for flexible packet processing and includes Broadsync HD technology for IEEE 802.1AS synchronization. The device integrates 1 Gbps and 2.5 Gbps SGMII interfaces to accommodate bandwidth growth and 802.11ac deployments. An on-chip 8051 microcontroller provides cable diagnostic capabilities and manages green energy-saving modes.
Verify the component authenticity by checking the manufacturer's marking against official datasheets. Confirm the specific suffix matches the required package and temperature range. Request a Certificate of Conformance from the supplier to ensure compliance with RoHS standards and traceability requirements before finalizing any acquisition.
Evaluate the requirement for 2.5 Gbps uplink speeds versus standard Gigabit ports when considering this model. Ensure the design accommodates the specific pinout of the compact package. Verify that the system architecture can support the integrated 8051 microcontroller if cable diagnostics or power management features are utilized in the final application.
This component belongs to Broadcom’s portfolio of high-performance Ethernet switches designed for dense networking environments. It addresses the need for increased bandwidth through 2.5 Gbps interfaces while maintaining compatibility with existing Gigabit infrastructure. The integration of field processors allows for complex packet manipulation within a small form factor.
Consult official Broadcom documentation for verified cross-reference part numbers. Do not assume pin-to-pin compatibility with other models without explicit manufacturer confirmation.
