AccessRunner
ADSL Modem Device Set for PCI Applications
Controller-less, Scalable, Discrete Multitone-based, G.dmt- and G.lite-
compliant, ADSL Modem Device Set for PCI Applications
Conexant’s AccessRunner
ADSL modem device set is compliant
with the full-rate ANSI T1.413 Issue 2 and ITU G.dmt (G.992.1)
ADSL standards, and with the splitterless ITU G.lite (G.992.2)
specification. This rate-adaptive solution is designed for controller-
less PCI desktop applications and supports downstream data rates
of up to 8 Mbps and upstream data rates of up to 1 Mbps.
The device set takes advantage of the processing power available
with most new computers by eliminating the need for a separate
microcontroller, resulting in a cost-effective solution suitable for
both G.dmt and G.lite applications. Host-based software provides
support for current industry standards for PPP over AAL5 over
ATM over ADSL and RFC 1483 for Windows 98 and Windows
2000.
The device set, as shown in Figure 1, consists of four chips:
PCI bus interface (AccessRunner P46 in a 176-pin TQFP)
DMT-based data pump (AccessRunner 11627 in a 176-pin
TQFP)
Analog front end (AccessRunner 20431 in a 32-pin TQFP)
Line driver (AccessRunner 20441 in a 16-pin SSOP or
32-pin TQFP)
