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, and so on.

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.

Macrovision Rev 7.1 (ADV7190 Only)

CGMS (Copy Generation Management System)

WSS (Wide Screen Signaling)

Closed Captioning Support

Teletext Insertion Port (PAL-WST)

2-Wire Serial MPU Interface

Supply Voltage 5 V and 3.3 V Operation

64-Lead LQFP Package

The ADV7190/ADV7191 can output Composite Video (CVBS),

S-Video (Y/C), Component YUV¹, 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.
