DMT Datapump
The CX11627 DMT datapump is a T1.413 Issue 2-, G.992.1- and
G.992.2-compliant Digital Signal Processor (DSP). The device
performs DMT modulation/demodulation, ATM transmission
convergence (TC), forward error correction (FEC) encoding/
decoding, data synchronization, and data interleaving. Control
and initialization of the datapump is done by the host PC as
part of the software drivers.
Analog Front End (AFE)
The CX20431 AFE is designed for use in full-rate and G.lite
ADSL modems. The receive path filters out unwanted echo and
boosts the wanted signal before performing an Analog-to-Digital
(A/D) conversion. The transmit path converts digital data to analog
signals and performs a smoothing operation before presenting the
signals to the line driver.
Line Driver
The integrated CX20441 line driver is more cost effective and
power sensitive than a discrete solution, and is optimized for
full-rate and G.lite ADSL modems. It has high bandwidth, low
noise and superior linearity.

AccessRunner USB ADSL Modem Device Set
Full-Rate and G.lite ADSL Modem Delivers End-to-End
Internet Connectivity
Conexant’s AccessRunner USB-based ADSL CPE chipset and PC
driver solution is optimized to address the growing demand for
high-speed Internet access. With a USB 1.1-compliant interface,
it takes advantage of the extreme ease-of-use and Plug-and-Play
nature of USB peripherals, making it ideal for both desktop and
notebook computers. AccessRunner is fully compliant with both
the full-rate ADSL (T1.413 Issue 2 and G.dmt) and the splitterless
G.lite (G.992.2) standards. Compliance ensures that products based
on the AccessRunner solution can address the existing installed
base and continued deployment of ADSL lines.
Conexant’s AccessRunner modem is an “always on” high-speed
broadband connection to the Internet. Using existing twisted
pair telephone lines, ADSL technology provides data rates over
