Conexant Systems Inc. (Nasdaq: CNXT) has introduced the industry's first octal (8-port) asymmetric digital subscriber line (ADSL) chipset to integrate each port's analog front end (AFE) and line driver (LD) into a single device.
Conexant's solution is also the first of its kind to include a reference design that can be used directly as a line card in central- office DSL access multiplexers (DSLAMs) that deliver high-speed Internet access services.
Priced below $20 per port in OEM quantities, Conexant's latest AccessRunner(TM) ADSL central-office chipset streamlines system design to cut total per-port system costs while reducing power requirements, eliminating analog crosstalk problems and dramatically reducing time-to-market schedules.
It is aimed at the growing market for low-power, high-density solutions that enable fast market entry for both new equipment suppliers and established competitors. Conexant introduced its new AccessRunner 9009 solution at the DSLCon Asia conference at the Hong Kong Convention Center, Aug. 28-31, 2000.
Conexant's AccessRunner 9009 solution supports 8 Mbps full-rate ADSL technology as well as 1.5 Mbps G.lite ADSL technology, which eliminates the need for telephone companies to install splitter equipment or special wiring at the customer premises. The company's low-power, high-density central-office ADSL solution is designed for use in DSLAMs, digital loop carriers (DLCs) and multi-tenant units (MTUs). These systems provide the core technology for concentrating a number of ADSL subscriber lines into asynchronous transfer mode (ATM) for transport over the broadband Internet infrastructure.
"Conexant's AccessRunner 9009 chipset is a full-featured octal solution that occupies a compact 1.3 square inch of board space per port. Also, with a system-level focus to reduce cost and increase density, the chipset integrates many analog and digital components and eliminates the need for three out of four power supplies normally used for line drivers," said Babak Nabili, senior product line manager for Conexant's ADSL central-office products. "At less than $20 per port, this is the lowest cost solution on the market and...
