CX90412/CX90411/CX90410
Conexant’s portfolio includes a comprehensive suite of semiconductor
solutions for broadband communications, enterprise networks, and the
digital home. The Conexant CX90412 Voice Coprocessor (VCP) compresses
and decompresses two channels of packet voice from telephone lines or
handsets and interfaces to a host network processor over a parallel interface
bus. The CX90412 is packaged in a 64-pin QFN.
The CX90410/CX90411 VCP compresses and decompresses one channel of
packet voice from a telephone line or handset and interfaces to a host network
processor over a parallel interface bus. The CX90411 is packaged in a 64-pin
QFN and CX90410 an 80-pin PQFP. CX90410 is pin compatible to CX9168
voice coprocessor. The host network processor can typically be a Conexant
CX821xx or CX86202 home network processor (HNP), an ADSL router or a
CX82310 single-chip ADSL router. When coupled with software provided with
the CX9041x, the HNP and VCP device set implements voice control functions
and network/communications protocols, and interfaces to a host computer over
an Ethernet or USB connection.
The CX9041x VCP interfaces to telephone handsets through subscriber
line interface circuit/subscriber line audio-processing circuit (SLIC/SLAC)
devices that provide the required analog control signals and line power to
the telephone, as well as analog-to-digital and digital-to-analog conversion.
Each channel of the CX90412 VCP can run compression and decompression
algorithms according to the ITU-T G.7xx series of codecs that are commonly
used in VoIP and VoDSL services.
The host network processor interfaces to the CX9041x VCPs through its
host interface bus and provides a platform on which voice control functions
and network or communications protocols may be implemented. Different
combinations of Foreign Exchange – Station (FXS) and Foreign Exchange
Office (FXO) applications can be easily supported.
The company’s broad portfolio of semiconductor products also includes client-
side DSL and cable modem solutions, home network processors, broadcast
video encoders and decoders, digital set-top box components and systems
solutions, and dial-up modems. In addition to its IEEE 802.11a/b/g-compliant
WLAN chipsets, software, and reference designs, Conexant offers a suite
of networking components that includes solutions for applications based on
HomePlugSM and HomePNA. Additional products include a complete line of
asymmetric and symmetric DSL central office solutions, which are used by
service providers worldwide to deliver broadband data, voice, and video over
copper telephone lines.
