Single-Chip Cable Modem Solution
DOCSIS™ 2.0-Based
CX24951
Conexant’s next generation cable modem solution
offers a DOCSIS 2.0-based single-chip modem while
providing dual software programmable network
processing engines
Conexant’s broadband communications portfolio includes a comprehensive
suite of semiconductor solutions that enable the digital home and information
network. 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 CX24951, Conexant’s DOCSIS 2.0-based single-chip cable modem
solution, provides backwards compatibility with the DOCSIS 1.1 and the
DOCSIS 1.0 standards. The world’s fastest, lowest power and smallest cable
modem solution, the CX24951, offers 500 MIPS of processing power while
consuming just 550mW in a 17mm x 17mm BGA package.
The CX24951 fully supports the new upstream physical-layer modulation
technologies A-TDMA (Advanced Time Division Multiple Access) and S-CDMA
(Synchronous Code Division Multiple Access) as specified in DOCSIS 2.0
standard. These new modulation techniques significantly increase upstream
cable bandwidth for data transmissions (up to 30Mbps) without requiring
any physical rebuilding of cable networks.
The CX24951’s 500 MIPS and software programmable dual processor architecture
with on-chip memory for cable MAC and application layer processing makes
it ideally suited for CableHome™ and PacketCable™ applications.
Dual Programmable Network Processors
The CX24951 utilizes the proven software programmable dual processor
architecture of its predecessor, the CX24943, and further boosts its
performance by increasing the instruction memory size to 128K bytes.
The CX24951 is pin compatible with the CX24943.
The dual network processing engine architecture offers real-time-critical
packet management processing and superior performance. The software
programmability of this architecture accommodates application specific
requirements, worldwide standards, and manufacturers’ unique value
added features for maximum flexibility.
