The Broadcom BCM5461SA2KQMG is a highly integrated Gigabit Ethernet transceiver designed to support 10BASE-T, 100BASE-TX, and 1000BASE-T standards. It offers flexible MAC interface options including GMII, RGMII, SGMII, SerDes, RTBI, and MII, making it adaptable to a wide range of networking applications. With both copper and fiber line-side interfaces, this transceiver ensures reliable connectivity across various physical media. Built on a 0.13μm CMOS process, it delivers low power consumption—less than 700 mW per port—while supporting advanced power management features such as Wake on LAN. Its on-chip low-voltage regulators and low EMI emissions further enhance its efficiency and performance in compact system designs.
Engineered for robust operation, the BCM5461SA2KQMG includes advanced diagnostic capabilities like a cable plant analyzer, automatic detection and correction of wiring issues, and link quality indication via LED. It supports jumbo packets up to 9 KB and features automatic MDI/MDIX crossover at all speeds, simplifying network setup. The device is fully compliant with IEEE 802.3 standards and includes IEEE 1149.1 JTAG boundary scan for testing. Available in multiple package types including 128-pin MQFP, 117-pin BGA, and 100-pin FBGA, it is well-suited for high-performance, space-constrained applications.
