Increased Performance
The CX24943 utilizes the proven architecture of its
predecessor, the CN9414, and boosts performance
by increasing the system processor speed to 225
MHz. The CX24943 Single-Chip Cable Modem IC
block diagram shows the major functional blocks
of the monolithic IC.
Conexant
’
s sixth-generation physical-layer
downstream receiver includes a 10-bit A/D that
accepts a direct IF signal (at 44 or 36 MHz) and
a 16/256 QAM demodulator with Annex A and B
forward error correction. The CX24943 also contains
an 11-bit D/A converter, which can accommodate
65 MHz of upstream bandwidth for EuroDOCSIS
and DVB applications, and a QPSK/16 QAM burst
upstream modulator. Conexant
’
s proven PHY
technology exceeds all DOCSIS
/EuroDOCSIS
1.0/1.1 requirements for low BERs in
noise-filled environments.
The CX24943 is the fastest solution in the industry
with integrated dual software programmable
network-processing engines on board. Its unique
packet management, unified memory architecture,
and advanced system buses, maximize performance
by allowing segmentation of real-time-critical
DOCSIS/EuroDOCSIS 1.0/1.1 functions from non
real-time-critical application processes. The
CX24943
’
s processor performance and unique
architecture enables DOCSIS/EuroDOCSIS 1.1 and
other software applications, including: firewall for
added security; routing for home networking;
or VoIP for low-cost IP telephony.
