LCD display engine goes from analog input to XGA/SXGA output

With the ADE3700 family from STMicroelectronics, you get an integrated solution that transforms conventional analog RGB signals into the signals and format you need to drive a TFT LCD panel. It supports resolutions up to SXGA at 75 Hz refresh rates, for 6- or 8-bit panels and single- or double-wide panel formats. The members of the family perform context-sensitive upscaling and downscaling, support on-screen display functions including bordering, shadows, fade-in and fade-out, and subwindows, and image-enhanced text. Within the display engine are a 9-bit A/D converter and PLL, clock and sync circuitry, and EMI-reduction functions such as per-pin delay, slew-rate control, and spread-spectrum clocking. Members of the pin-compatible family differ in interface support and extra display functions; the 128-lead LQFP package that houses the family members is designed to be used on a low-cost, two-layer PC board. In lots of 20,000 units, the ICs range between US$5 and $7, depending on the specific model.
