ADSL integrated communications processor solution

14 August 2002 Telecoms, Datacoms, Wireless, IoT

Analog Devices' Pathfinder client premises equipment (CPE) chipset with ADSL integrated communications processor is the first to integrate the communications processor and ADSL digital pump on a single chip. The high level of integration reduces the ADSL router bill of materials by up to 40% according to the company. ADI's Pathfinder is aimed at the small office/home office (SOHO) and residential mass-market applications including ADSL bridges/routers, ADSL USB-Ethernet combo devices, ADSL wireless gateways and ADSL Integrated Access Devices (IADs). Pathfinder is also a platform for providing emerging value-added broadband services like stateful firewall, and Fast Path QoS.

"Analog Devices' Pathfinder is a giant step forward in meeting the industry need for high performance, cost-effective, full function broadband access solution," said Brian McAloon, group vice president and general manager, ADI. "Pathfinder-based ADSL bridge/router products will set new price/performance standards to spur further growth in the DSL market and to benefit the end user."

ADI's Pathfinder-based solution is comprised of two chips - the AD6680 and AD6480. The AD6680 provides Layer-1 to Layer-7 processing for ADSL applications on a single chip, including ADSL, ATM processing, bridging/routing, stateful firewall, QoS/bandwidth management, network management and PC Card support for WLAN/802.11b. It directly interfaces with the integrated line driver/receiver AFE (AD6480). Analog Devices offer complete software and reference platforms for bridge/router, wireless gateways and integrated access devices (VoIP/VoATM) applications.

In addition, ADI's Pathfinder solution combines some of the market leading features of ADI's AD6489, a high performance broadband communications processor, with the ADSL PHY.
