BCM5328MA1KQM

Product Summary

The Broadcom BCM5328MA1KQM device is a highly integrated solution. It 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. This device contains eight full-duplex 10BASE-T/100BASE-TX Fast Ethernet transceivers, each of which performs all of the physical layer interface functions for 10BASE-T Ethernet on Category 3, 4, or 5 Unshielded Twisted Pair (UTP) cable and 100BASE-TX Fast Ethernet on Category 5 UTP cable.
