ADSL MODEM MANUFACTURERS BENEFIT FROM LSI LOGIC'S CHIPSET.
"Our SoC and mixed-signal expertise has resulted in an optimal price-performance combination for modem manufacturers, saving them 30% in bill-of-materials (BOM) costs compared to typical solutions," said Kumar Sivakumar, senior director of the DSL Products business unit, LSI Logic. "At the same time, our superior SpeedREACH technology and highly integrated network processor provide the performance levels needed to address bandwidth bottlenecks, security issues and new service needs for DSL service providers."
Delivering superior performance across all loops, the HomeBASE Ethernet modem has demonstrated the highest packet throughput-even at high line rates of 8Mbps downstream and 800kbps upstream-in both bridge and router mode when sending 64-byte short packet full duplex (the most stressful packet test, which requires greater processing power). In addition, the reference modem is in compliance with both the DSL Forum's TR-048 performance test and the new stricter rate/reach limits being proposed by the U.S. telephone companies. The modem is interoperable with DSLAMs and compliant with all ADSL standards, including G.dmt and G.lite, with support for Annex A and B.
The HomeBASE ADSL Ethernet chipset consists of a fourth-generation analog front end (AFE, the SpeedREACH AR8202), a high-performance network processor (AR900) and an Ethernet PHY (L80225). To reduce the total BOM, cost and power, the SpeedREACH AFE integrates 14-bit linear converters, a +5V line driver, a line receiver and a digitally controlled crystal oscillator (DCXO), and consumes less than 1W. The ADSL network processor integrates the DMT engine, an ARM9 processor, a hardware-based ATM SAR, and a 10/100 Ethernet controller with scatter gather DMA, SDRAM controller and a proprietary bus bridge architecture. The company's field-proven IEEE 802.3-compliant dual-mode 10/100 Ethernet PHY completes the data distribution on the LAN side.
In addition to bridging and routing, the AR900 network processor has the capacity to run critical firewall and security software, and customizable element management tools. The processor features both an MII bus and a proprietary external bus bridge, which is highly configurable to interface with HPNA, USB or 802.11 PHYs. Use of this high-performance, single-processor core simplifies the task of programmers who are further aided by the inclusion of a open-source, royalty-free, Linux-based software stack.
Giuseppe Staffaroni, executive vice president of the LSI Logic Consumer Products Group said, "The ability to offer technologies supporting convergence products in the consumer market gives LSI Logic customers a 'one-stop-shop' advantage. An increasing number of OEMs are designing combo boxes and early residential gateways that mix-and-match video, voice and data technologies. LSI Logic's HomeBASE ADSL solution augments the company's portfolio of technologies that enable cable modems, satellite, cable and terrestrial set-top boxes, gaming consoles, DVD and DVR players/recorders, and other devices that will play a vital role in the networked digital home."
The HomeBASE chipset can also address service provider requirements for product differentiation, such as voice, video and data distribution capabilities when used with LSI Logic's ZSP digital signal processing (for VoIP applications), Ethernet, USB, wireless LAN, and video products. LSI Logic's experience in developing complex system-on-a-chip designs, coupled with a strong standard product portfolio allows manufacturers to address a wide range of requirements for the broadband access market.
