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.
The BCM6410 standard compliant firmware includes power
optimization features such as the Power Crest™ that reduces line drivers
power consumption.
The BCM6410 12-channel DSL digital transceiver IC is supplied in a
27mm x 27mm Plastic BGA (336-ball) package. The BCM6420 12channel xDSL AFE IC is supplied in a 23mm x 23mm Plastic BGA (208ball) 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, M, and L, ITU G.992.5
(ADSL2+) and Annex A, B, and M giving complete support for full- and
double-rate ADSL, extended upstream ADSL2, Reach Extended READSL, and up to 29-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 fractional S operations.
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.
