AccessRunner CX82310 Single-Chip ADSL Router

Broadband Internet Connectivity
The Conexant AccessRunner CX82310 Single-Chip ADSL Router is optimised to address the growing demand for high-speed Internet access, and it does so as a single, highly-integrated and cost-effective solution.

Featuring a USB 1.1-compliant interface and an IEEE 802.3-compliant Ethernet MAC interface to provide connectivity options, the CX82310 does not rely on host PC drivers, and thus is not limited by them. The result is extreme ease-of-use with active auto selection of the interface and simultaneous operation of both USB and Ethernet. All setup and provisioning is accomplished via a simple intuitive Web interface which further enhances the user experience.

The CX82310 is built upon a scalable architecture and is fully compliant with full-rate ADSL (T1.413 Issue 2 and G.dmt standards) and the ‘splitterless’ G.Lite (G.992.2) standards, including Annex A (ADSL over POTS) and Annex B (ADSL over ISDN). This broad level of compliance ensures that products based on the AccessRunner can address the existing installed base and continued deployment of ADSL lines. Telephone companies, for example, can deploy full-rate, splitterless full-rate as well as G.lite to the consumer.

A single-chip router, the CX82310 allows an “always-on” high-speed broadband connection to the Internet. It uses existing twisted-pair telephone lines to deliver data rates at more than 100 times the speed of conventional dial-up modems, and without the interruptions that can plague telephone service. Data transfer rates of up to 8 Mbps downstream and 1 Mbps upstream make it the ideal solution for high-bandwidth applications for corporate networks, Internet and video delivery.

Networking support includes both bridge and router modes. The router mode includes advanced features such as Network Address Translation (NAT), Dynamic Host Protocol (DCHP) and Routing Information Protocol (RIPv2) processor, ADSL DMT Engine, Analogue Front End (AFE) and Line Driver.

Through the use of a flash file system, firmware upgrades are easily managed. This allows for simple, reliable product updates or feature enhancements.
A high-performance, 16-bit parallel expansion bus is available for additional functionality. This expansion bus provides a glueless interface to PCMCIA 802.11b wireless system. Additionally, the expansion bus can be used to interface to a V.92/V.90 backup system.

The newest member of Conexant’s AccessRunner family, the CX82320 modem device integrates all of the hardware functions of a USB controller, ADSL discrete multi-tone (DMT) engine, analog front end (AFE), and line driver on a single-chip. This comprehensive device combines the most cost-effective solution with the design simplicity of single-chip integration. The CX82320 ADSL modem device is fully compliant with both the full-rate ADSL (T1.413 Issue 2 and G.dmt) and the splitterless G.lite (G.992.2) standards.

Conexant’s CX82320 modem device provides an “always on” high-speed broadband connection to the Internet. Using existing twisted pair telephone lines, ADSL technology provides data rates over 100 times the speed of a traditional analog modem, without an interruption in telephone service.

AccessRunner ADSL/V.92/HomePNA 2.0/Ethernet-PCI Modem Device Set

A Four-in-One Solution
Conexant has integrated four of the most commonly used communications technologies ADSL, V.92, Home Phoneline Networking and Ethernet into one robust solution that can support any combination of the four functions concurrently. This solution lets OEMs use just one PCI slot to support all communication needs in the PC.

Our industry leadership has enabled us to bring the first such combination solution to the marketplace. Conexant is a member of the DSL Forum, which supports interoperability. Our V.90/V.92 technology is the leading 56 Kbps technology in the world. We are a founding member of HomePNA, an industry group spearheading efforts to create standards-based products for easy-to-use, reliable and affordable home connectivity.

Conexant’s SuperComms™ Architecture
This solution is based on Conexant’s SuperComms architecture, which enables board manufacturers and PC OEMs to combine communications functions in a single board. The SuperComms architecture uses a PCI bus interface, buffering and an arbiter to manage all the interrupt handling for ADSL, V.92 modem connectivity, HomePNA, and Ethernet operations.

PCI Controller
Conexant’s P51 PCI controller is a bridge between the PCI bus and the other devices. It integrates the system-side device for V.92, DSL interfaces, and incorporates 2 MACS for HomePNA and Emulated Local Area Network (ELAN). The P51 complies with the PCI 2.2 specification and supports power management.

DMT Datapump
The CX11627 DMT datapump is a DSP that complies with T1.413 Issue 2, G.992.1 and G.992.2. The device performs DMT modulation/demodulation, TC, FEC, encoding/decoding, data synchronisation and data interleaving. The software drivers enable the host PC to control and initialise the datapump.

Analogue Front End
The CX20431 AFE is designed for use in full-rate and G.lite ADSL modems. The receive path filters out unwanted echo and boosts the wanted signal before performing an A/D conversion. The transmit path converts digital data-to-analogue signals and performs a smoothing operation before presenting the signals to the line driver.

Line Driver
The integrated CX20441 line driver is more cost-effective and power-sensitive than a discrete solution and is optimised for full-rate and G.lite ADSL modems. It has high-bandwidth, low noise and superior linearity.

HomePNA 1.0 or 2.0 Physical-Layer Analogue Front End
The combo modem supports either of the specifications proposed by the HomePNA 1.0 (1 Mbps) or HomePNA 2.0 (10 Mbps). The phoneline network is an Ethernet-compatible LAN that uses existing telephone wiring to link computers and devices without interrupting phone service. Products that comply with these specifications and combine home networking with high-speed Internet access will enable users to enjoy networked gaming over one phoneline. Appliances such as digital TV Set Top Boxes, Internet phones and digital cameras also can be connected via phoneline.

V.92 Modem with SmartDAA™
The V.90/V.92 data modem receives data at up to 56 Kbps and sends at up to V.34 rates. A V.80 synchronous access mode supports host-controlled communication protocols with H.324 support. The modem solutions also features Wake-on-Ring, Caller ID detection and digital PBX line protection.
The silicon Data Access Arrangement (DAA) solution, SmartDAA, replaces a portion of the DAA segment of a modem or other communications device, and provides all of the interface circuitry, off-hook relay, loop current holding, impedance matching and ring detection needed for a complete solution. It is designed to meet domestic and international line-interface requirements.
Based on Conexant’s patented Digital Isolation Barrier (DIB) technology, this silicon DAA product eliminates the need for the costly analogue transformers, relay and opto-isolators that are typically used in discrete DAA implementations.
