Analog Devices Inc. ADV7182 10-Bit SDTV Video Decoder

Analog Devices ADV7182 10-Bit SDTV Video Decoder automatically detects and converts standard analog baseband video signals compatible with worldwide NTSC, PAL, and SECAM standards into a 4:2:2 component video data stream. The resulting video data stream is compatible with the 8-bit ITU-R BT.656 interface standard. ADV7182's digital video output stream interfaces easily to a wide range of MPEG encoders, codecs, mobile video processors, and Analog Devices' digital video encoders. External HS, VS, and FIELD signals can offer timing references for LCD controllers and other videos ASICs. The accurate 10-bit analog-to-digital conversion delivers professional-quality video performance for consumer applications with true 8-bit data resolution. The analog video inputs accept both single-ended, pseudo-differential, and fully differential composite video signals as well as S-Video and YPbPr video signals, supporting a wide range of consumer and automotive video sources.
