The
BCM6410
and
BCM6420
devices are the first of
Broadcom's new BladeRunner™ generation of low-power DSL
chipsets designed for very high-density and functionally rich
DSLAM and DLC systems.
Powered by Broadcom's ultra-high performance FirePath™
communications processor, optimized for xDSL algorithms, the
BCM6410's
fully programmable digital design serves as a
platform for a low-power and high-density digital transceiver IC.
BladeRunner's unique PowerCrest™ power optimization reduces
line driver power consumption regardless of the line driver used.
It also supports system-wide algorithms only available on a
purely software-based system.
The
BCM6410
12-channel DSL digital transceiver IC is supplied
in a 27 mm x 27 mm Plastic BGA (336-ball) package. The
BCM6420
12-channel xDSL AFE IC is supplied in a 23 mm x
23 mm Plastic BGA (208-ball) package.
The firmware for the
BCM6410/BCM6420
chipset supports
ANSI T1.413 issue 2, ITU G.992.1 Annexes A, B, C, and I, ITU
G.992.2 (G.lite), ITU G.992.3 (ADSL2) Annex A, B, J, and L, and
ITU G.992.5 (ADSL2+) giving complete support for full- and
double-rate ADSL, extended upstream ADSL2, Reach Extended
RE-ADSL, and up to 27-Mbps ADSL2+.
Future firmware upgrades will track future standards evolution,
extend interoperability, and provide higher-layer network
functions. Upgrades are supplied to customers as required for all
firmware variants, using the same hardware design for
all Annexes.
CPE InterOperability
The BladeRunner solution has proven interoperability with a
broad range of ADSL CPEs and supports extended rate-reach
performance, as well as dual latency and S = 0.5 operation.
Host Messaging Interface Definition
The functionality of the BladeRunner chipset is accessed via a
flexible messaging interface. This interface is supported on the
local processor port connection and over the in-band
management link. A detailed and comprehensive definition of
this interface is available to customers and full design-in
assistance is provided, including example host codes and
graphical user interfaces (GUIs).
Reference Line Card Designs
Broadcom has designed a number of working line cards with
generic system connectivity to suit different form factors and
channel counts. These serve as references for customer designs,
demonstrate the high channel density capability of the Broadcom
solution, verify CPE interoperability, and showcase the viability
of low-cost volume production. These boards are readily
manufactured in high volume at low cost. Broadcom can provide
line card design expertise as an integral part of the design support
activity.
Evaluation Systems
Broadcom has produced several evaluation systems that use the
reference line card designs to quickly prototype working multi-
channel ADSL modems. This allows customers to evaluate the
benefits of using Broadcom's BladeRunner ADSL chipset, and
provides a development platform for system/product
prototyping.
Software Development Environment
Broadcom has created a sophisticated software development
environment with which to design, build and verify the software
base for its FirePath™ processor core and its ADSL applications.
This environment includes a comprehensive commercially
available tool chain of processor simulators, assemblers,
optimizing compilers, and debugging tools. The software
environment includes a robust real-time operating system and
flexible software architecture. Using the tool chain, additional
functionality can be added to the chipset's firmware tailored to a
customer's specific requirements by Broadcom or by the
customer
−
all the necessary support is provided.
Technology White Papers
Broadcom has created a comprehensive base of innovative
technology during development of its ADSL products, on which
white papers are available. This technology relates to new design
processes, the FirePath processor architecture, low-power
hardware designs, system-wide power management techniques,
optimized software algorithms, and unique ADSL traffic-
carrying techniques.
