Overview
Network Processing and VoIP VoIP Voice Coprocessor 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...
