High Speed ADSLplus Chipset with
Integrated Wireless LAN
Conexant’s portfolio includes a comprehensive suite of semiconductor
solutions for broadband communications and the digital home.
The CX94610 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 CX94615 (ADSL2plus
Chipset with Integrated Wireless LAN and Voice). The chipset includes a highly
integrated analog front end (AFE) and a single-chip network processor with
802.11a/b/g MAC and baseband functionality. The CX94610 includes all the
interfaces required to enable feature-rich DSL CPE platforms.
An integrated 802.11 a/b/g MAC/baseband processor in the CX94610 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 CX94610 has been designed to accommodate advanced wireless
features such as push-button Wi-Fi Protectd 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 CX94610 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 CX94610 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 CX94610 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 CX94610 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 Wi-Fi
processor, virtual private network (VPN) engine, and hardware ATM SAR, are
integrated to support compute intensive tasks. The software solutions for the
CX94610 include full support for advanced features such as IPTV quality of
service (QoS), advanced firewall, and DSLHome™, the DSL Forum’s initiative to
standardize and simplify the provisioning and configuration of the DSL gateway.
