CX94615
Conexant’s portfolio includes a comprehensive suite of semiconductor
www.DataSsoheluett4ioUn.csomfor broadband communications and the digital home.
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®/HomePNA™ 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 a secure, stable path for future upgrades and features.
At the center of the CX94615 chipset is a high performance ARM-based RISC
processor core, which supports industry standard operating systems such as
Linux® as well as Conexant’s full-featured, advanced ISOS® software suite.
To assist the processor, additional hardware engines, including a dedicated
