GENERAL DESCRIPTION
The ADV7282/ADV7282-M are versatile one-chip, multiformat
video decoders. The ADV7282/ADV7282-M automatically
detects standard analog baseband video signals compatible with
worldwide NTSC, PAL, and SECAM standards in the form of
composite, S-Video, and component video.
The ADV7282 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 ADV7282-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 ADV7282/ADV7282-M accept
single-ended, pseudo differential, and fully differential signals.
The ADV7282/ADV7282-M contain a deinterlacer (I2P con-
verter) and short to battery detection capability with two STB
diagnostic pins. The ADV7282 provides four analog inputs.
The ADV7282-M provides six analog inputs and three general-
purpose outputs.
The ADV7282/ADV7282-M are programmed via a 2-wire, serial
bidirectional port (I²C compatible) and is fabricated in a 1.8 V
CMOS process. The LFCSP package option makes the decoder
ideal for space-constrained portable applications.
