Distinguishing Features
Conexant’s Next Generation Cable
Modem Solution Offers a Higher Level
of Integration, Increased Performance,
and Lower Power Dissipation
The InfoSurge
family of products, supporting broadband
cable modem applications, presents the industry with yet
another example of Conexant
’
s ability to exceed the needs
of a growing market segment. The CX24943, Conexant
’
s next
generation single-chip cable modem IC, reduces the cost of
consumer premise equipment (CPE) by providing a highly
integrated, robust and flexible solution.
The CX24943 leads the industry in cost-effectiveness through
its high level of integration, advanced process technology,
extremely small package and low power consumption. It offers
a dual software programmable network-processing engine
architecture, allowing for real-time-critical packet management
processing for superior performance. The software programma-
bility of this architecture accommodates application specific
requirements, worldwide standards, and manufacturers
’
unique
value added features, for maximum flexibility. The CX24943 is
software compatible with its predecessor, the CN9414.
A multitude of interfaces are integrated into the chip, including
an embedded IEEE 802.3 Media Access Controller (MAC) with a
Media Independent Interface (MII), a USB 1.1 communications
transceiver, and a host interface. The CX24943 supports internal
and external PC cable modems, home networking gateway
products, IP (Internet Protocol) telephony products, and digital
set-top boxes.
