NEWPORT BEACH, Calif.--Conexant Systems Inc. here today rolled out its second-generation modem chip set for full-rate Asymmetric Digital Subscriber Line (ADSL) services in personal computers. The four-chip set ADSL solution will enable PC makers to offer up to 8 megabit-per-second Internet access over standard telephone lines, said Conexant.
The new AccessRunner client-modem chip set conforms to all the ADSL standards with the ability to "address full-rate ADSL services that are being deployed today based on T1.413 while being ready to support the newer standards as they are deployed next year," said Nick Burd, director of ADSL products at Conexant.
The chip set implements the modem's controller and WAN/LAN protocol functions in a host-based driver in the PC. Conexant said this configuration enables the most cost-effective solution possible for offering ADSL as a bundled PC feature. The AccessRunner product full-rate ANSI T1.413 Issue 2, ITU G.dmt (G.992.1) and the splitterless ITU G.lite (G.992.2) specification. Conexant said AccessRunner is the first in a series of chip sets planned for home networking and broadband Internet access.
The new chip set's controllerless PCI architecture will enable Conexant to incrementally add new features for home networking using its LANfinity technology, Burd said.
Conexant said its AccessRunner solution includes a Discrete Multi-tone (DMT)-based data pump, a PCI bus interface, an analog front end (AFE) and a line driver.
The AccessRunner chip set is now available in sample quantities with volume deliveries slated to begin in December. The chip set is priced at $35 each in quantities of 10,000. The ADSL DMT data pump and PCI bus interface are each housed in a 176-pin thin quad-flat pack (TQFP), and the AFE chip is packaged in a 32-pin TQFP. The line driver comes in a 16-pin shrinksmall outline package (SSOP).
