®
The Marvell 88E3015/88E3018 devices are the fourth
®
generation Marvell DSP-based physical layer trans-
ceivers for Fast Ethernet applications. The devices con-
tain all the active circuitry to convert data streams to
and from a Media Access Controller (MAC) and the
physical media. The 88E3015/88E3018 devices incor-
porate IEEE 802.3u Auto-Negotiation in support of both
100BASE-TX and 10BASE-T networks over twisted-
pair cable in full-duplex or half-duplex mode.
The 88E3015/88E3018 devices both support the
Reduced Gigabit Media Independent Interface (RGMII),
and the Media Independent Interface (MII).
The 88E3015/88E3018 devices feature a mode of oper-
ation supporting IEEE compliant 100BASE-FX fiber-
optic networks. Additionally, the 88E3015/88E3018
devices implement Far-End Fault Indication (FEFI) in
order to provide a mechanism for transferring informa-
tion from the local station to the link partner that indi-
cates a remote fault has occurred in 100BASE-FX
mode.
The 88E3015/88E3018 devices feature the Marvell Vir-
®
tual Cable Tester (VCT™) technology, which enables
IT managers and networking equipment manufacturers
to remotely analyze the quality and characteristics of
the attached cable plant.
The 88E3015/88E3018 devices use advanced mixed-
signal processing and power management techniques
for extremely low power dissipation and high port count
system integration. The 88E3015/88E3018 devices are
manufactured in an all CMOS process.

The 88E3018 device, housed in a 64-pin QFN package,
offers a pin-upgradeable path toward future Gigabit
Ethernet PHY designs. The 88E3018 device includes
support for IEEE 1149.1 JTAG Standard Test Access
Port and Boundary Scan. The 88E3108 device is avail-
able in Industrial grade (RoHS 6/6 compliant package
only)
The 88E3015 device, housed in a 56-pin QFN package,
provides a cost-efficient, increased board savings
option to the 88E3018.
