Overview
The TVP5150AM1IPBSQ1 is an ultralow-power NTSC/PAL/SECAM video decoder produced by Texas Instruments. This device is designed to convert NTSC, PAL, and SECAM video signals into digital 8-bit ITU-R BT.656 format, with discrete syncs also available. It is available in a space-saving 32-terminal TQFP package, making it ideal for applications where power efficiency and compact design are crucial. The decoder features an optimized architecture that allows for ultralow power consumption, consuming 115 mW under typical operating conditions and less than 1 mW in power-down mode, significantly extending battery life in portable devices.
