Renesas Technology Corp. introduced the R8J66954BG, which offers single-chip implementation of signal processing functions from front-end signal input to later stages such as signal output to a liquid crystal display (LCD) panel.
Sample shipments of the device, designed for North American LCD digital TVs, will begin in December 2007 in Japan.
The R8J66954BG supports the Advanced Television Systems Committee (ATSC) digital broadcasting system used in North America and also incorporates video decoder and closed caption functions compatible with the National Television System Committee (NTSC) analog TV broadcasting system.
Features of the R8J66954BG include:
- Single-chip implementation of main LCD digital TV processing, including Moving Picture Experts Group (MPEG) decoding and panel signal processing.
On-chip functions include North American digital broadcast signal vestigial sideband (VSB) front-end processing, MPEG decoding processing, noise reduction circuitry, de-interlacer circuitry, closed caption and data slicer functions, plus natural color matrix (NCM) performing color management as an LCD panel signal processing function.
In addition, noise reduction, de-interlacer and NTSC luminance/chrominance (Y/C) separation circuits incorporate a 3D processing function for high-picture-quality video display. Functions previously performed by six chips, such as digital signal processing and NTSC signal processing can be implemented by a single R8J66954BG.
- Support for NTSC broadcasting system and various interface standards. In addition to the NTSC analog broadcast system used in North America, the R8J66954BG also supports component type, composite type and S-signal type interface standards used worldwide.
According to Renesas, this makes it possible to process a video signal from a device that has recorded an analog broadcast program, while the compatibility with a variety of interface standards helps simplify set development.
The package used is a 345 pin plastic ball grid array (PBGA).
