| Transceiver Solutions Alaska(R) Quad Gigabit Ethernet Transceivers 88E1040/S, 88E1041/S, 88E1042H PRODUCT OVERVIEW The Marvell Alaska family of Gigabit Ethernet (GbE) over copper transceivers are the industryOs lowest power, smallest form factor, highest performance, and highest port density solutions in volume production. Targeted at high-density GbE switches, the Alaska Quad transceivers are single-chip devices containing four independent GbE PHYs on a single monolithic IC. Each transceiver performs all of the physical layer functions for 100BASE-TX and 1000BASE-T full or half duplex Ethernet on category 5 (CAT 5) twisted pair cable, and 10BASE-T full or half duplex Ethernet on CAT 3, 4 and 5 cable. The Alaska Quad devices (88E1040S, 88E1041S and 88E1042H) offer additional support of 1000BASE-X through an integrated 1.25 GHz Serializer/Deserializer (SERDES).

Through integrated SERDES technology, the devices also offer optional support for 1000BASE-SX/LX Gigabit fiber standards, on a per port basis, enabling mixed-media Gigabit switches. These devices support five different PHY/MAC interface options: GMII, RGMII, SGMII, TBI, and RTBI. 10/100/1000 Mbps Ethernet MAC 10/100/1000 Mbps Ethernet MAC 10/100/1000 Mbps Ethernet MAC 10/100/1000 Mbps Ethernet MAC RJ45 Alaska Quad PHY Magnetics RJ45 RJ45 RJ45 Media Types: 10BASE-T 100BASE-TX 1000BASE-T 10/100/1000 Mbps Ethernet MAC 10/100/1000 Mbps Ethernet MAC 10/100/1000 Mbps Ethernet MAC 10/100/1000 Mbps Ethernet MAC Fiber Optics Alaska Quad PHY Fiber Optics Fiber Optics Fiber Optics Media Types: 1000BASE-LX 1000BASE-SX MAC Interface Options: GMII/MII (88E1040/88E1040S and 88E1041/88E1041S only) TBI (88E1040/88E1040S and 88E1041/88E1041S only) RGMII RTBI SGMII Serial Interface (88E1040S, 88E1041S and 88E1042H only) MAC Interface Options: GMII/MII (88E1040S and 88E1041S only) TBI (88E1040S and 88E1041S only) RGMII RTBI Fig 2.
