1. Conexant Shipping Newest Cable Modem Chip
Conexant Systems has said that it is shipping its InfoSurge CX24943 cable
modem chip, a single monolithic system on a chip design that includes dual
processing engine, an 802.3 10/100 MAC with a MII for home networking, a
USB 1.1 transceiver, a host interface to accommodate VoIP and wireless
networking, and an integrated upstream/downstream PHY. The processors
include an ARM9 application processor running at 225 MHz and a ARM9 MAC
processor running at 144 MHz. In the PHY, the downstream receiver includes
a 10-bit A/D that accepts a direct IF signal (at 44 or 36 MHz) and a
4/16/64/256 QAM demodulator with Annex A, B, and C FEC. It also includes
an 11-bit D/A converter that can accomodate 65 MHz of bandwidth for
EuroDOCSIS and DVB apps, and a QPSK/16 QAM burst upstream modulator.
The technology delivers 29,000 packets per second throughout regardless of
packet size. The cable line rate of 38 Mbps can be maintained even with
packets as small as 160 bytes.
The chip can be used for Ethernet, USB, PCI, and computer controlled cable
modems, multifunction home networking products, set-tops, SOHO equipment,
and VoIP products. It can also be used for software apps used in router
products such as security firewalls, advanced bridging and routing
protocols, NAT, DHCP servers, and wireless 802.11b access points.
The application software can be implemented to upgrade deployed InfoSurge
cable modem devices, improving performance and functionality.
Conexant is offering a reference design for DOCSIS/EuroDOCSIS 1.0/1.1
Ethernet, USB, or PCI cable modems.
The CX24943 chip is packaged in a 17mm x 17mm 228-pin PBGA. It goes for
$26.50 per unit in quantities of 10,000.

2. ChanneLogics Introduces CMTS Bandwidth Module
ChanneLogics has introduced a CMTS capacity planning and forecasting module
that can perform real-time data collection, service level/policy
management, capacity planning, forecasting and trending, statistics
reporting, and dynamic bandwidth re-allocation. Operators are able to view
actual and anticipated bandwidth usage patterns by subscriber, blade, CMTS,
and interface in detail. The technology is scheduled for availability in
January.
