Broadband Access - Client Side
DSL Solutions
High Speed ADSLplus Chipset
with Enhanced INP and USB 2.0
Conexant’s portfolio includes a comprehensive suite of semiconductor
solutions for broadband communications and the digital home.
The CX94410 is part of a new family of pin compatible CPE products
from Conexant designed to leverage common DSP firmware, software,
and hardware efforts across multiple applications from DSL bridges to
wireless enabled DSL Integrated Access Devices (IADs). Other products
in this family include the CX94610 (ADSLplus Chipset with Integrated
Wireless LAN) and the CX94615 (ADSL2plus Chipset with Integrated
Wireless LAN and Voice). The CX94410 chipset includes a highly integrated
analog front end (AFE) and high speed network processor along with all the
key interfaces required to enable feature-rich DSL CPE platforms.
The CX94410 handles connections to an Ethernet PHY, Ethernet switch,
or HomePlug®/HomePNA™ through a 10/100 Ethernet MAC with MII
interface. Support for USB 2.0 host/device applications is available
to attach peripherals such as print servers, network attached storage,
