InfoSurge Cable Modem Reference Designs
Conexant’s Cable Modem Reference Designs include all the silicon
and software necessary to create a complete subscriber modem
that can support all popular worldwide cable-modem standards.
Manufacturers can add their own box and branding, while retaining
the unprecedented flexibility to software-upgrade their platforms
to customize feature sets, support new standards or migrate to
future capabilities such as Internet Protocol (IP) telephony and
home networking. The heart of the Conexant cable modem
reference design is the InfoSurge CN9414 single-chip cable modem
IC, the industry’s only solution to feature a programmable MAC
layer that manufacturers can software-upgrade or re-program to
support DOCSIS, EuroDOCSIS, Digital Video Broadcast (DVB)
and proprietary cable modem standards.
CN9420CM DOCSIS Cable Modem Reference Design
Conexant’s CN9420CM cable modem reference design is a complete
DOCSIS external cable modem built upon the InfoSurge family’s
CN9414 single-chip cable modem integrated circuit. The CN9414’s
high-degree of integration helps to significantly reduce the overall
cost of a cable modem. At the same time, the industry’s first
programmable cable MAC architecture provides the ultimate
in flexibility and upgradeability.
The CN9420CM provides a baseline for a variety of implementations,
including DOCSIS 1.0, DOCSIS 1.1, and IP telephony. The CN9420CM
may also be used as an effective evaluation platform that provides
headers for Joint Test Action Group (JTAG) and RS-232, as well as
expandability for BER testing, constellation visibility, and IP telephony.
Features
• InfoSurge CN9414 single-chip cable modem
- Highest level of integration
- Programmable MAC architecture
• Complete solution including all software
- DOCSIS-certifiable code
- @Home-approvable code
- WQHL-certifiable Windows drivers

CX9440CM DOCSIS PCI Cable Modem Reference Design
Conexant’s CX9440CM PCI non-host-based cable modem reference
design is a complete DOCSIS solution built upon the InfoSurge
family’s CN9414 single-chip cable modem integrated circuit. The
CN9414’s high degree of integration helps to significantly reduce
the overall cost of a cable modem, while the programmable cable
MAC architecture provides the ultimate in flexibility and upgrade-
ability. The CX9440CM offers the industry a path for integrating
cable modems inside the PC, opening up new channels and
significantly reducing provisioning complexity.
