CX24430/1/2/3
Conexant‘s highly integrated, single IC, MPEG-2/DVB-compliant, decoder/transceiver solution for digital cable television receivers
Conexant’s broadband communications portfolio includes a comprehensive suite of semiconductor solutions that enable the digital home and information network. Adding to this impressive line up are the CX24430/1 and CX24432/3 Interactive Cable TV Decoder ICs. These highly-integrated products combine a high-speed broadband cable modem and an interactive TV broadcast service decoder onto a single chip. It is a breakthrough in IC integration that will allow set-top box manufacturers to offer advanced, fully-interactive broadband home gateways or other set-top appliances for the price of an entry-level product that only receives TV broadcasts. The CX24431/3 versions support NDS Videoguard® conditional access technology. The CX24430/2 ICs combine the industry’s highest performance DOCSIS® cable modem with the company’s third generation interactive TV decoder technology. This new platform optimizes performance by partitioning cable modem tasks between a dedicated 32-bit ARM940T processor and programmable software MAC. At the same time, digital TV broadcast service decoding and set-top box interactive applications are hosted by a second, dedicated high performance 275MIPS main system processor. The cable modem section of the device also allows for narrowband interactivity based on DAVIC 1.2 and 1.5 as well as the DVS 178 and DVS 167 specifications.
