The [http://focus.ti.com/docs/prod/folders/print/tvp5151.html TVP5151 ] device is an ultralow-power NTSC/PAL/SECAM video decoder. Available in a space-saving 48-terminal PBGA package or a 32-terminal TQFP package, the TVP5151 decoder converts NTSC, PAL, and SECAM video signals to 8-bit ITU-R BT.656 format. Discrete syncs are also available. The optimized architecture of the TVP5151 decoder allows for ultralow power consumption. The decoder consumes 138-mW power under typical operating conditions and consumes less than 1 mW in power-down mode, considerably increasing battery life in portable applications. The decoder uses just one crystal for all supported standards. The TVP5151 decoder can be programmed using an I2C serial interface.
