Functional
Description
AL9M802 is an AverLogic's
advanced Multimedia Networking Controller. It is an ASSP
solution targeted for networking consumer multimedia and
surveillance applications. It implements all necessary
functions in hardware to provide customer flexible
peripheral interfaces. By using this ASSP along with
other companion chips is the best combination to meet
customer¡¦s system requirements. It is mainly designed
to support 802.11x, HomePlug 1.0/AV and Ethernet for
networked multimedia transmission. The data such as
graphics, MPEG A/V, audio and voice can be transmitted
by AL9M802 efficiently. By applying AverLogic's
proprietary network schemes for multimedia, such as
Dynamic Stream Support, Parameterized QoS and ALMM PCF
Operation, it provides high-quality MPEG audio &
video transmission for isochronous and time-sensitive
multimedia applications. It also has an 802.11x MAC
interface so that it can be used to communicate with
commercial WiFi PHY products. It also supports 802.3
compliant Ethernet MAC which can access to commercial
Ethernet PHY directly. AL9M802 enables high speed and
digital wireless data connectivity for networking
multimedia or other broadband application. |
