Integrated Broadband Communications Processor
ANALOG DEVICES CONTINUES TO STRIKE OUT BOLDLY WITH PRODUCTS AND TECHNOLOGY FOR THE BROADBAND ERA
Emerging Broadband Landscape As the demand for voice, data and video convergence escalates in the residential and office markets, broadband is becoming a pervasive force driving bandwidth explosion. Simple
connectivity through high-speed pipes will not be enough to attract and retain discerning
subscribers - particularly telecommuters and SOHO subscribers. The ability to understand key market and industry trends such as the emergence of service-level agreements (SLAs) will
determine the success of service providers as they strive to bring converged communications to
consumer premises.
Next-Generation Network Requirements In order to address these evolving market requirements, equipment manufacturers need highly
integrated cost-effective silicon coupled with a powerful software suite. This solution needs to be flexible and scaleable, provide IP services and Quality of Service (QOS) Bandwidth management,
Wire Speed Security/VPN with bundled voice and data services.
Convergence Communications Processors The answer to accomplishing all of this rests with communications processing chipsets. An integrated blend of ICs and software, these processors leverage a single convergence platform
with high throughput routing and bridging functionality to link any physical layer device with
higher-layer network processing that is required to address voice, data and video.
As part of its leadership initiative to make inroads in both the wired and wireless segments of the
broadband market, ADI made two strategic acquisitions during 2000.
In 2000, ADI purchased Thomas Neuroth AG, an Austrian-based engineering design firm
specializing in symmetric DSL (SDSL), with experience in developing products for HDSL and G.SHDSL applications.
Communications Processor Group Last November, ADI also acquired Chiplogic Inc., a developer of processors and software
focused in the convergence communications processing space. While ADI has concentrated efforts on the physical layer, Chiplogics development activities emphasize Layer 2+
technologies with domain expertise in Systems, VLSI and DSP. This complementary melding of
technological expertise will enable ADI to achieve new levels of integration with broadband access and voice network processing.
The initial result of the Choplogic acquisition (now known as the Communications Processor Group) is ADIs development of the AD6489 and AD6689 communications processors, a system-
on-a-chip hardware and software solution, which expands the companys broadband solutions
portfolio. This processor family consists of two product versions: one, which is data-only and known as AD6489, and is targeted at SME (Small and Medium Enterprise) security/VPN
gateways and routers, while the second device known as AD6689 provides voice and data and is
designed for a number of applications, including routers, integrated access devices, SOHO (Small Office/Home Office) and other application-specific gateways, line cards and multiservice
concentrators.
AD6x89 Communications Processors The AD6x89 family offers a flexible architecture, security features and powerful, modular
software that ensure high performance. The WAN-independent architecture provides equipment
manufacturers the flexibility to interface with DSL, cable, WLL (wireless local loop) and Ethernet in the First Mile (EFM), allowing them to address multiple market segments. In
addition, system developers can take advantage of the modular software and a powerful API to
customize the architecture to application-specific requirements and increase their ROI. A Convergence Exchange Platform (CEP), which is a system-level implementation of the AD6489,
enables developers to work on and integrate their custom software applications for the AD6489
and AD6689 prior to its availability in silicon.
Technology Value Proposition AD6489 family of products offers a significant value proposition to system vendors both in terms
of the architecture and functionality for next generation CPE Equipment.
Security AD6x89 has a combination of hardware accelerators for Encryption and Authentication coupled with software like Crypto libraries and IKE running on a RISC engine. The portfolio of security
hardware engines include DES/3DES algorithms as well as SHA-1 and MD-5 Authentication
algorithms.
QoS Engines AD6x89 solution provides Fast Path Forwarding Engines to accomplish QoS for Bandwidth Management / Differentiated Services this is needed to put real- time sensitive data like voice
and video (residential and business) and to prioritize mission- critical data traffic (business). The AD6489 solution for QoS provides functionality needed to achieve Fast Path Data Flow for: Parsing Packet Classification Traffic Conditioning Route Lookup Scheduling
Service Level Agreements (SLAs) AD6x89 provides features for IP Services and Policy Management that would enable SLAs -
amongst other things service providers can provide leased-line type of service to customers while
having the ability to dynamically use additional available bandwidth.
Powerful Processing Platforms The AD6x89 devices are a single platform with distributed and specialized RISC engines to
handle all of the Voice Processing, Layer 2 to Layer 7 tasks and System Applications. The
benefits of this include: Reduced BOM Smaller Footprints Reduce Power Requirements Increased Performance Low Latency
Comprehensive Software A comprehensive, pre-packaged software suite includes: Device Drivers Base Level Integrated Software Optional Add-on Features System Applications Real-time Kernel (long-term)
This significantly reduces the burden on the system vendors by avoiding dealing with multiple
sources for various stacks and the associated integration issues. This also reduces the overall
development cost while providing time-to-market advantages.
Reference Platforms ADI provides complete reference platforms for the popular system applications. The reference
platforms have the complete software integrated and tested for interoperability. The idea is to
allow the system vendors to adopt the reference platform, as it is if they choose to and reduce
their time-to-market by allowing them to focus on system level differentiating features.
Hardware Interfaces Hardware interfaces have been provided to gluelessly connect to other chips and provide system
level applications like 802.11b, HomePNA, DOCSIS Modem, chassis- based, Ethernet uplink etc.
This significantly reduces the overall BOM of the systems.
WAN/PHY Independence The AD6x89 processing solutions can work in conjunction with any Layer 1 (WAN) technology.
The architecture also makes them adaptable to ATM, IP and Frame Relay.
Complete Vertical Solutions ADI offers complete vertical solutions for system applications through integration where
possible. Also in some areas like ADSL, ADI can offer complete vertical solution for CPE & CO
applications including AFE, Digital Engine and Layer 2+ Processors. This reduces the burden on
the system vendor by having a single source for all of the main components of the system.
Leading the Process Curve ADI strong relationships with leading foundries like TSMC coupled with the strong back-end
expertise of the CPG group enables CPG group to stay ahead of the competition in the process
technology curve. This gives significant advantages over competition: Higher Performance Lower Power Smaller Area Lower Device Cost
As a new generation of information appliances takes advantage of the power of broadband
networks and residential gateways, ADI will continue to shape its product development strategy
to address these needs. The AD6489/AD6689 products are just the tip of the iceberg, as the
company continues to leverage its DSP and analog expertise, and solid understanding of the
entire signal processing chain in the broadband communications sector.
