Marvell Alaska 88E3015/88E3016/88E3018
Single-Port Fast Ethernet Transceivers
PRODUCT OVERVIEW
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.
The 88E3015, 88E3016, and 88E3018 all support the Reduced Gigabit Media Independent Interface (RGMII), with the 88E3015
and 883018 also supporting the Media Independent Interface (MII). They all feature a mode of operation supporting IEEEFRPSOLDQW%$6();¿EHURSWLFQHWZRUNV$GGLWLRQDOO\WKHGHYLFHVLPSOHPHQW)DU(QG)DXOW,QGLFDWLRQ)(),LQRUGHU
to provide a mechanism for transferring information from the local station to the link partner that indicates that a remote
fault has occurred in 100BASE-FX mode.
The Alaska 88E3015, 88E3016, and 88E3018 feature the Marvell Virtual Cable Tester ® (VCT™) technology, which enables
IT managers and networking equipment manufacturers to remotely analyze the quality and characteristics of the attached
cable plant. Additionally, the devices use advanced mixed-signal processing and power-management techniques for extremely
low power dissipation and high port count system integration.
The 88E3015, 88E3016, and 88E3018 devices can operate from a single 2.5v or 3.3v supply. They are offered in low-pin
count QFN packages which reduce board space and are ideal for small form-factor applications. In addition, the 88E3016
and 88E3018 are the only single-port FE PHYs available in the industry which are pin-upgradeable to Gigabit Ethernet.

APPLICATIONS
Despite the existence of advanced Gigabit Ethernet, 10/100 Ethernet maintains a strong presence in corporate networks, in
small home networks and in various media devices. The Marvell Alaska single-port FE PHY transceivers provide connectivity
solutions for a variety of applications including DVRs, game consoles, media vaults, video cameras, printers, and notebook
or desktop PCs. The Alaska 88E3015, 88E3016, and 88E3018 offer low-power dissipation, enabling system manufacturers
to decrease their system costs by reducing power supply requirements.
