Broadband Internet Connectivity
Conexant's broadband communications portfolio includes a comprehensive
suite of semiconductor solutions that enable the digital home and information
network. The Conexant Voice solution consists of a CXP9168 or a CXP9468
Voice Coprocessors capable of processing one/two independent voice
channels together with a CX821xx Home Network Processor or CX82310
ADSL router based on a powerful ARM940 core. Each channel of the DSP
can run compression and decompression algorithms according to the ITU-T
G.7xx series of codecs that are used today in VoIP and VoDSL services. The
DSP interfaces to one/two telephone handsets through third-party SLIC/SLAC
(Subscriber Line Interface Controller/Subscriber Line Access Controller)
devices that provide the correct analog control signals and power to the
telephone, as well as analog-to-digital and digital-to-analog conversion.
A number of different third-party devices may be used together with the
DSP through the use of external programmable interface logic.
The Home Network Processor interfaces to the DSP through its host interface
bus and provides a platform on which voice control functions and network
or communications protocols may be implemented. The Home Network
Processor contains a powerful ARM940 core with integrated instruction and
data caches. A dedicated external memory bus allows use of 2, 4 or 8 Mbytes
of standard SDRAM or SRAM devices, while a flash program memory device
is connected using the host interface bus. The Home Network Processor also
integrates two 10/100 Ethernet MACs with industry standard MII interfaces
that allow connection to a range of physical networking media, including
Ethernet, HPNA and HomePlug Powerline devices. A USB slave interface is
also available for connection to a personal computer.
