How to setup tvp5151 video decoder
From IGEP - ISEE Wiki
What is?
The 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.
The TVP5151 decoder converts baseband analog video into digital YCbCr 4:2:2 component video.
