Overview
The ADV7182WBCPZ-RL, produced by Analog Devices Inc., is a 10-bit, standard definition (SDTV) video decoder designed to automatically detect and convert standard analog baseband video signals into a digital 4:2:2 component video data stream. This decoder supports worldwide NTSC, PAL, and SECAM standards and is compatible with the 8-bit ITU-R BT.656 interface standard. It features differential inputs and can handle single-ended, pseudo-differential, and fully differential composite video signals, as well as S-Video and YPbPr video signals. The ADV7182WBCPZ-RL is fabricated in a 1.8 V CMOS process, ensuring low power dissipation and high functionality, making it ideal for consumer and automotive applications.
