The TVP5150AM1PBS is an ultralow-power NTSC/PAL/SECAM Video Decoder. The TVP5150AM1 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 TVP5150AM1 decoder allows for ultralow power consumption. The decoder uses just one crystal for all supported standards. The TVP5150AM1 decoder can be programmed using an I 2C serial interface. The TVP5150AM1 decoder converts baseband analog video into digital YCbCr 4:2:2 component video. Composite and S-video inputs are supported. The TVP5150AM1 decoder includes one 9-bit analog-to-digital converter (ADC) with 2x sampling. Sampling is ITU-R BT.601 (27.0MHz, generated from the 14.31818MHz crystal or oscillator input) and is line locked. The output formats can be 8-bit 4:2:2 or 8-bit ITU-R BT.656 with embedded synchronization.
