OVERVIEW
The BCM6410 and BCM6420 devices are the first of Broadcom's new BladeRunnerTM 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 FirePathTM 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 CrestTM 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.
