GENERAL DESCRIPTION
The ADV7280/ADV7280-M are versatile one-chip, multiformat
video decoders. The ADV7280/ADV7280-M 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 analog video inputs of the ADV7280/ADV7280-M accept
single-ended signals. The ADV7280 provides four analog inputs;
the ADV7280-M provides eight analog inputs. The ADV7280
and ADV7280-M support I2P conversion.
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.
