GENERAL DESCRIPTION
The ADV7190/ADV7191 is part of the new generation of video
encoders from Analog Devices. The device builds on the perfor-
mance of previous video encoders and provides new features such
as, Digital Noise Reduction, Gamma Correction, 4
Oversam-
pling and 54 MHz operation, Average Brightness Detection,
Chroma Delay, an additional Chroma Filter, etc.
The ADV7190/ADV7191 supports NTSC-M, NTSC-N (Japan),
PAL N, PAL M, PAL-B/D/G/H/I and PAL-60 standards. Input
standards supported include ITU-R.BT656/601 4:2:2 YCrCb
in 8- or 16-bit format.
The ADV7190/ADV7191 can output Composite Video (CVBS),
S-Video (Y/C), Component YUV
** or RGB. The analog
component output is also compatible with Betacam, MII
and SMPTE/EBU N10 levels, SMPTE 170M NTSC and
ITU-R.BT 470 PAL.
