The MAX2986 powerline transceiver utilizes state-of-theart
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® 1.0 devices.
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 optimum
performance. Hence, this device is aimed at applications
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 technique
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 management.
The MAX2986 operates with IEEE® 802.03 standard
media independent interface (MII), reduced media independent
interface (rMII), buffered FIFO data communication,
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.
