Toshiba Launches New Family Of Analog Video Front-End Processors

8-Mar-05

Toshiba America Electronic Components, Inc. (TAEC announced the first two devices in a new family of analog video front-end processors targeted at television, set-top box, audio/video (A/V) receiver and video converter/switch applications. Designated TB1305FG and TB1308FG, the new integrated circuits (ICs) are component switch front-end processors that perform component video switching and pre-processing for analog-to-digital converters (ADCs). They integrate input terminals for two or three YCbCr (or RGB) signals, a selector switch with one output terminal, an automatic synchronization processor, a real-time format detector for video formats up to 1080p and UXGA, an ADC pre-filter, and a proprietary dummy HD/VD output for picture stabilization in the absence of a video input. Samples are currently available.ìThe highly integrated TB1305FG and TB1308FG component switch front-end processors offer ideal solutions for televisions, set-top boxes and other A/V products that process high-bandwidth component video, said David Cruikshank, Senior Business Development Engineer for digital consumer products in the ASSP Business Unit at TAEC. ìThe innovative dummy HD/VD output, real-time format detection, and automatic synchronization are some of the features that not only simplify and speed design but also enhance the end-user experience.î He added that the new ICs complement Toshibaís other digital consumer offerings, including tuner ICs, comb filter front-end processors, HDMI receiver, HDTV decoders, microprocessors and single-chip LCD-TV ICs. Additional new products in this family are under development and will be announced in the future.Highlights of the TB1305FG and TB1308FG component switch front-end processors include the following:Feature two-input (TB1305FG) or three-input (TB1308FG) and one-output YCbCr or RGB component switch (also available for one CVBS or YC signal) Offer a 4.2 to 31MHz variable pre-filter for the A/D converter that reduces defects and distortion in the video imageProvide real-time format detection for various television and computer video formats up to 1080p and UXGAFeature automatic synchronization to reduce software design time and save engineering resourcesProvide dummy HD/VD outputs to maintain a stable picture when no video signal is inputSupport I2C bus controlHoused in lead-free, pin-compatible QFP48 packagingPricing and Availability:Samples of both devices are currently available. Volume production of TB1308FG began this month with volume production of TB1305FG planned to start in March 2005. TB1305FG is priced at $3.00 each in 10,000-piece quantities. TB1308FG is priced at $3.25 each in 10,000-piece quantities.
