10-Bit, 4× Oversampled SDTV Video Decoder with Differential Inputs and Deinterlacer

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 converter) 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.
