The Marvell® Alaska® 88E3015, 88E3016, and 88E3018 are Marvell’s fourth-generation DSP-based physical layer (PHY) transceivers for Fast Ethernet (FE) applications. The devices contain all the active circuitry required to convert data streams to and from a Media Access Controller (MAC) and to and from the physical media. The 88E3015, 88E3016, and 88E3018 devices incorporate IEEE 802.3u auto-negotiation, supporting both 100BASE-TX and 10BASE-T networks over twisted-pair cable in full-duplex or half-duplex mode
