Overview
The ADV7182ABCPZ-RL, produced by Analog Devices Inc., is a versatile, one-chip, multiformat video decoder designed to automatically detect and convert standard analog baseband video signals into digital video data streams. This device supports worldwide NTSC, PAL, and SECAM standards and converts these signals into a 4:2:2 component video data stream compatible with the 8-bit ITU-R BT.656 interface standard. The ADV7182ABCPZ-RL features a 10-bit analog-to-digital converter (ADC) and an on-chip differential to single-ended converter, allowing it to accept single-ended, pseudo-differential, and fully differential composite video signals, as well as S-Video and YPbPr video signals. This makes it ideal for a wide range of applications, including automotive, industrial, and consumer electronics.
