ADSL chip set cuts costs, extends reach. (Leading Edge).(Brief Article)

EDN Europe, September, 2002 by Prophet, Graham

ADSL HAS IN A SHORT TIME become a commodity market in which key differentiators are bill of materials and software flexibility, according to LSI Logic. The company has introduced its HomeBase ADSL chip set, which both increases performance and reduces bill of materials. The three-chip set, which interfaces directly to an Ethernet port on the customer-premises side, comprises the AR8202 analogue front end, the AR900 network processor, and the L80255 Ethernet physical-layer chip. LSI says it kept the physical layer and front end separate because the physical layer is a high-volume, stand-alone function that has cost benefits as a discrete part, and keeping the analogue front end separate isolates the sensitive analogue-signal-processing circuitry and allows the...
