Product Summary

The BCM5325MA2KQM is a five-port 10/100 switch with on-chip packet buffer. The BCM5325MA2KQM is a highly integrated solution. The BCM5325MA2KQM combines all the functions of a high-speed switch system—including packet buffer, PHY transceivers, media access controllers, address management, and a non-blocking switch fabric—into a single 0.18μ CMOS device. It complies with the IEEE 802.3, 802.3μ, and 802.3x specifications, including the MAC control PAUSE frame and autonegotiation subsections, providing compatibility with all industry-standard Ethernet and Fast Ethernet devices.
