CX90411 Datasheet | Conexant Systems

Network Processing and Vo IP Vo IP Voice Coprocessor CX90412/CX90411/CX90410 Conexant’s portfolio includes a prehensive suite of semiconductor solutions for broadband munications, enterprise networks, and the digital home. The Conexant CX90412 Voice Coprocessor (VCP) presses and depresses 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 presses and depresses 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 patible 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/munications protocols, and interfaces to a host puter 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 pression and depression algorithms according to the ITU-T G.7xx series of codecs that are monly used in Vo IP and Vo DSL 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 munications protocols may be implemented. Different binations of Foreign Exchange - Station (FXS) and Foreign Exchange Office (FXO) applications can be easily supported. The pany’s...
