The MAX2986 powerline transceiver utilizes state-of-the-

art CMOS design techniques to deliver the highest level

of performance and flexibility. This highly integrated

design combines the media access control layer (MAC)

and the physical layer (PHY) in a single chip. The

MAX2986 digital baseband and its companion device,

the MAX2980* analog front-end (AFE), offer a complete

high-speed powerline communication solution that is fully

compatible with third-party HomePlug

The MAX2986 digital transceiver utilizes Maxim’s

advanced OFDM powerline engine with adaptive data

rates up to 14Mbps. The MAX2986’s open architecture

allows extensive programmability, feature enhancement

capability, and improved testability in the MAC for opti-

mum performance. Hence, this device is aimed at appli-

cations such as local area networks (LANs), audio,

voice, home automation, industrial automation, and

broadband-over-powerline (BPL), as well as spectral

shaping and tone notching capability, providing an

unparalleled level of flexibility to conform to the disparate

local regulatory bodies. Maxim’s modified OFDM tech-

nique allows shaping of power spectral density of the

transmitted signal arbitrarily to accommodate any

desired subcarrier set and to place spectral nulls at any

unwanted frequency location. The automatic channel

adaptation and interference rejection features of the

MAX2986 guarantee outstanding performance. Privacy

is provided by a 56-bit DES encryption with key manage-

ment.

The MAX2986 operates with IEEE 802.03 standard

media independent interface (MII), reduced media inde-

pendent interface (rMII), buffered FIFO data communica-

tion, IEEE 802.03 compatible 10/100 Ethernet MAC, or

USB 1.1 interfaces. These interfaces allow the MAX2986

to be paired with almost any data communication

devices to use in a variety of information appliances.
