¡El AR8327 is a highly integrated seven-port Gigabit Ethernet switch with non-blocking switch fabric, a high-performance lookup unit with 2048 MAC address, and a four-traffic class Quality of Service (QoS) engine. ¡El AR8327 has the flexibility to support various networking applications. ¡El AR8327 is designed for cost-sensitive switch applications in wireless AP routers, home gateways, and xDSL/cable modem platforms. ¡El AR8327 integrates 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 0.11 um CMOS device. It complies with 10BASE-Te, 100BASE-Tx & 1000BASE-T specifications, including the MAC control, pause frame, and auto-negotiation subsections, providing compatibility with all industry-standard Ethernet, Fast Ethernet & Gigabit Ethernet networks. ¡El AR8327 device contains five full-duplex 10BASE-Te/100BASE-TX/1000BASE-T transceivers and 10BASE-Te/100BASE-TX can run at half duplex, each of which performs all of the physical layer interface functions for 10BASE-Te Ethernet on Category 5 unshielded twisted-pair (UTP) cable and 100BASE-TX Fast/Gigabit Ethernet on Category 5 UTP cable. ¡El remaining 2 ports feature a standard GMII/RGMII/MII/Serdes interface to allow connection to a host CPU in PON/xDSL/Cable/Wifi/Fiber routers. ¡El media access controllers on the AR8327 also support Jumbo Frames which are typically used for high-performance connections to servers because they offer a smaller percentage of overhead on the link for more efficiency.MDC/MDIO or EEPROM interfaces provide easy programming of the on-chip 802.1p QoS
