Description
The Marvell Alaska family of Gigabit Ethernet (GbE) transceivers, including the 88E1518-NNB2 model, are known for being the industry's lowest power, smallest form factor, highest performance, and highest port density solutions. The 88E1518-NNB2 is a single-channel GbE transceiver optimized for the mobile computing market. It supports 100BASE-TX and 1000BASE-T Ethernet on category 5 (CAT 5) twisted pair cable and 10BASE-T Ethernet on CAT 3, 4, and 5 cable. The device also offers additional support for 1000BASE-X through an integrated 1.25 GHz Serializer/Deserializer (SERDES).
