The CX94615 is part of a new family of pin compatible CPE products from Conexant designed to leverage common DSP firmware, software, and hardware efforts across multiple applications from DSL bridges to wireless enabled DSL integrated access devices (IADs). Other products in this family include the CX94410 (ADSLplus Chipset with Enhanced INP) and the CX94610 (ADSLplus Chipset with Integrated Wireless LAN). The chipset includes a highly integrated analog front end (AFE) and a single-chip network processor with both integrated voice and 802.11a/b/g MAC and baseband functionality. The CX94615 includes all the interfaces required to enable feature-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 components and improves manufacturing and quality with a repeatable and easily tunable Wi-Fi front end. The CX94615 has been designed to accommodate 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 VoIP solution, running complex 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 SmartDAA product family. The CX94615 handles connections to an Ethernet PHY, Ethernet switch, or HomePlug/HomePNATM 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 ,
