CX94615 Datasheet | Conexant Systems

ure-rich DSL CPE platforms. An integrated 802.11 a/b/g MAC/baseband processor in the CX94615 interfaces to Conexant’s CX5022x family of Wi-Fi® transceivers and RF front-end modules. The optimized Wi-Fi architecture reduces the number of ponents and improves manufacturing and quality with a repeatable and easily tunable Wi-Fi front end. The CX94615 has been designed to acmodate advanced wireless Features such as push-button Wi-Fi Protected Setup (WPS) to easily and securely connect to wireless devices, and full Smart Antenna support for reliable Wi-Fi coverage with both data and multimedia streams. The PCM and SPI bus on the CX94615 can be used to connect external codecs and SLICs to the internal voice DSP allowing a 2FXS/1FXO Vo IP solution, running plex algorithms such as G.729ab, G.726 or G.711 on each channel. The programmable architecture of the CX94615 allows for voice upgradeability to other codecs and provides an upgrade path for emerging wide-band codec support. Additional channels of voice can be added to the CX94615 using the Conexant CX9041x family of voice co-processors. A cost effective FXO option is available with integrated support for the field proven Conexant Smart DAA product family. The CX94615 handles connections to an Ethernet PHY, Ethernet switch, or Home Plug®/Home PNA™ through a 10/100 Ethernet MAC with MII interface. Support for USB 2.0 host/device applications is available to attach peripherals such as print servers, network attached storage, cameras, or other USB input devices. Both parallel and serial flash (SPI) support is included in the CX94615 for maximum design flexibility. The device interfaces to high speed SDRAM using a 16/32-bit wide connection and includes additional GPIOs for further expansion. The CX94615 incorporates a flexible dedicated DSP , which supports multiple DSL standards including ADSL, ADSL2, ADSL2plus (Annexes A, B, M, I, J and L), using proven firmware to reduce time-to-market, and is fully programmable to give OEMs...
