Overview
The TVP5151PBSR is an ultralow-power NTSC/PAL/SECAM video decoder produced by Texas Instruments. This device is available in a 32-terminal TQFP package and is designed to convert NTSC, PAL, and SECAM video signals into digital YCbCr 4:2:2 component video. The decoder supports both composite and S-video inputs and features a high-speed 9-bit analog-to-digital converter (ADC) with 2× sampling, adhering to the ITU-R BT.601 standard. The TVP5151PBSR is notable for its ultralow power consumption, consuming 138 mW under typical operating conditions and less than 1 mW in power-down mode, making it ideal for battery-powered applications.
