Powered by Broadcom’s ultra-high performance FirePath™ communications processor and optimized xDSL algorithms, the BCM6411 programmable digital design serves as a platform for highdensity multi-DSL digital transceivers. The BCM6411 12-channel DSL digital transceiver IC is supplied in a 27 mm x 27 mm plastic BGA (336-ball) package. The BCM6421 12channel xDSL AFE IC is supplied in a 23 mm x 23 mm plastic BGA (208-ball) package. Both devices are pin-compatible replacements for the first-generation BCM6410 and BCM6420 chipset. The single-build firmware for the BCM6411/BCM6421 chipset supports auto-detected ANSI T1.413 Issue 2, ITU G.992.1 Annex A, B, C, I, and ADSL Quad Spectrum, ITU G.992.2 (G.lite), ITU G.992.3 (ADSL2) Annex A, B, L, and M, and ITU G.992.5 (ADSL2+) Annex A, B, and M (Double Upstream) giving complete support for high data rates up to 40 Mbps downstream and 5 Mbps upstream. The BCM6411 soft modem implementation enables future firmware upgrades and evolution to new standards in very short design cycles. Upgrades are supplied to customers as required for all firmware releases using the same hardware design for all Annexes. CPE Interoperability The BladeRunner solution has proven interoperability with a broad range of ADSL and ADSL2 CPEs. Detailed interoperability and performance reports are available to customers via DocSAFE or upon request. Host Messaging Interface Definition The BladeRunner chipset is managed via a high-level messaging interface supported either on a local processor or over the in-band management channel. Comprehensive definition of the Host Messaging Interface is available to customers and full design-in assistance is provided, including example host code and graphical user interfaces. Reference Line Card Designs The BCM96438 is a 1U IP-DSLAM “pizza box” featuring 48 lines of ADSL2+ with generic 100/1000BASE-T Ethernet uplink connectivity, providing a reference for customer designs. The BCM96438 board demonstrates the high channel density capability of the Broadcom solution, verifying CPE interoperability, and showcases the viability of low-cost volume production. Broadcom provides line card design expertise as an integral part of the design support activity. Evaluation Systems Broadcom has produced several evaluation systems that use modular 12port 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. Utilizing the toolchain, Broadcom tailors the chipset firmware’s functionality to meet customers’ specific requirements. Product Documentation Broadcom provides customers with comprehensive documentation to support the reference designs ranging from data sheets, application notes, schematics, Gerber files, PCB layout files, BOM, and technical reference manuals. All documentation is available from DocSAFE: Broadcom’s secure, web-based document management system. For more information, contact your local Broadcom sales representative.
