Controller-Based Modem for Embedded Applications
Conexant’s broadband communications portfolio includes a comprehensive
suite of semiconductor solutions that enable the digital home and information
network. Dial-up modems continue to be the predominant method of
communication for the embedded market.
The CX06833 modem is ideal for country-specific embedded
applications such as POS Terminals, Set-top Boxes, Metering, Building
Automation, Gaming, Ruggedized Notebooks, Remote Site Management
and any other application that requires a robust dial-up modem solution.
The device integrates the microcontroller, digital signal processor, memory and
support for a discrete DAA. The CX06833 supports either serial or parallel host
interface operation and it is available in a 144-pin TQFP package.
The CX06833 modem features data/fax/Telephone Answering Machine (TAM)
and optional full-duplex speakerphone with up to 56 kbps analog data modem
operation and 14.4 kbps fax modem operation. The V.92 modem includes
Quick Connect, Modem-on-Hold
™
and PCM Upstream. The CX06833 is also
available in V.34 or V.32bis options.
