USB Broadcast Audio/Video Decoder Including USB and DIF Interfaces




The CX23102 chipset brings Conexant's long heritage of audio and video capture solutions to systems that enable universal serial bus architectures. This device integrates all the functions required to perform television and external A/V capture on personal computers or consumer electronic devices.

The integrated worldwide video and audio decoders can be used to create cost-effective analog, hybrid, or combo capture solutions utilizing the DIF and TS interfaces. The CX23102 can support capture of one single analog stream, two digital transport streams, or a combination of analog and digital streams. In addition, analog, hybrid, and combo configurations may be used in conjunction with hardware MPEG encoders, e.g., the CX23417.
