TV receiver combines tuning, analog demodulation in small package

Santa Clara, Calif.—Xceive Corp. is sampling the XC4000 series of integrated hybrid silicon tuners for the terrestrial television and PC-TV market.

The XC4000 is a single-chip hybrid analog and digital TV tuner combining both tuning and analog demodulation functions in an ultra-small 7mm x 7mm, 48-pin QFN package.

The XC4000 provides can tuner performance to the PC-TV market. The XC4000 signal-to-noise-ratio (SNR) and phase noise match can tuner performance while providing a lower noise figure and higher AGC range, resulting in higher quality video image and a better end-user experience.

Universal to all Xceive tuners, the XC4000 delivers Xceive’s QuickTune technology, providing ultra fast per channel signal detection that allows for a complete channel scan of more than 100 channels in less than two seconds. ChannelVista is Xceive's “virtual tuner” technology that provides multiple- picture-in-picture (PIP) capabilities, allowing the viewer to watch up to 12 video channels simultaneously or to have their favorite channel “list” visualized on screen easing their channel selection.

It integrates all the SAW filters and video/audio demodulation to achieve a low BOM. The architecture and technology minimizes tuner-to-tuner and channel-to-channel performance variations and achieves very tight tolerances resulting in reduced customer product returns.

With its on-board DSP controller, the tuner supports worldwide television standards including PAL, NTSC, DVBT, ATSC, and QAM64 catering to the needs of the global TV and PC-TV market.

The XC4000 is both pin and BOM compatible with Xceive's XC3000 and XC2000 series of RF-to-broadband tuners.

Availability: Production quantities will begin shipping in the third quarter of 2007.
