Conexant samples broadcast A/V decoders for PCTV applications

Newport Beach, Calif.—Conexant Systems Inc. has introduced a family of broadcast A/V decoders targeted at PCTV applications, which allow consumers to watch television on personal computers.

The CX2310X decoders enable the capture of analog and digital broadcast streams on personal computers through an integrated USB interface. Key features include support for consumer infrared (CIR) functionality, which allows consumers to operate multimedia PCs and TVs connected to cable or satellite set-top boxes (STBs) with a single remote control.

To enable CIR functionality, an infrared transmission cable is connected from the STB to the PCTV tuner card in the computer. Once this is complete, the multimedia PC remote can be used to manage functions such as changing television channels, browsing photos on the PC, and volume control.

The broadcast decoders comply with worldwide audio and video broadcast standards, and include automatic standard-detection and configuration capabilities. They are offered in various configurations and can be used to capture a single analog stream, two simultaneous digital TV transport streams, or a combination of analog and digital broadcast programming.

Features include 10-bit video A/D converters, a full 10-bit video data path, a multi-tap horizontal and vertical scaler, and hue, brightness, saturation, and contrast controls. In addition, the decoders have integrated anti-aliasing technology and noise reduction filters to improve image clarity. They are packaged in a 132-pin QFN package.

Pricing: $6 each in volume quantities.
Availability: Sampling now; volume quantities expected in September 2008.
