Description

The ADV7280/ADV7280-M are versatile one-chip, multiformat video decoders. They automatically detect standard analog baseband video signals compatible with worldwide NTSC, PAL, and SECAM standards in the form of composite, S-Video, and component video. The ADV7280 converts the analog video signals into a YCrCb 4:2:2 video data stream that is compatible with the 8-bit ITU-R BT.656 interface standard. The ADV7280-M converts the analog video signals into an 8-bit YCrCb 4:2:2 video data stream that is output over a mobile industry processor interface (MIPI®) CSI-2 interface. The ADV7280/ADV7280-M are programmed via a 2-wire, serial bidirectional port (I2C compatible) and are fabricated in a 1.8 V CMOS process. The LFCSP package option makes these decoders ideal for space-constrained portable applications.
