Analog Devices Inc. ADV7283 SDTV Video Decoders

Analog Devices Inc. ADV7283 SDTV Video Decoders are offered as versatile one-chip, multiformat video decoders that 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. ADV7283 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.

ADV7283's six analog video inputs accept single-ended, pseudo-differential, and fully differential signals. The deinterlacer (I²P converter) enables the device to output video in a progressive format. Fabricated in a 1.8V CMOS process, the ADV7283 is programmed via a 2-wire, serial bidirectional port (I²C compatible). Designed in a space-saving LFCSP surface-mount, RoHS-compliant package, the ADV7283 is available in an automotive-grade rated over the -40°C to 105°C temperature range, as well as a −40°C to 85°C temperature range, making the device ideal for both automotive and industrial applications.
