Single chip scan rate converter supports 1080p high definition applications

Toshiba’s new TC90240XBG significantly simplifies the delivery of high quality television picture output by providing a combination of scan conversion and comprehensive picture management functionality without the need for software programming. The device uses LVDS connectivity to accommodate the 50Hz or 60Hz video input from a suitable MPEG decoder and scalar IC and to deliver the 100Hz or 120Hz video output.

The TC90240XBG accepts 8-bit or 10-bit WXGA 768p or full HD 1080p input signals in RGB, YCbCr and YPbPr formats and can provide WXGA 768p or full HD 1080p 8-bit or 10-bit RGB output. As well as colour space conversion, the device offers frame interpolation functions including motion vector measurement and motion judder reduction. Picture management functions include colour management, RGB gamma correction, frame rate control dither and a YCbCr to RGB matrix.

Integrated memory control and interfaces allow the TC90240XBG to address up to 1Gbit of external 533MHz, 16-bit DDR2-SDRAM and 32kbyte of external EEPROM.

Supplied in a 564-pin PBGA package, the TC90240XBG has a board mounting footprint of just 31mm x 31mm. Power supply voltages are 1.2V for the logic and PLL/clock generation and 3.3V for the LVDS interfaces and other I/O.
