GENERAL DESCRIPTION
The ADV7194 is an integrated Digital Video Encoder that con-
verts digital CCIR-601/656 4:2:2 10-bit (or 20-bit or 8-/16-bit)
component video data into a standard analog baseband television
signal compatible with worldwide standards. Additionally there
is the possibility to input video data in 3× 10-bit YCrCb progres-
sive scan format to facilitate interfacing devices such as progressive
scan systems.

There are six DACs available on the ADV7194, each of which
is capable of providing 4.33 mA of current. In addition to the
composite output signal there is the facility to output S-Video
(Y/C Video), RGB Video, and YUV Video. All YUV formats
(SMPTE/EBU N10, MII, or Betacam) are supported.
The on-board SSAF (Super Subalias Filter) with extended
luminance frequency response and sharp stopband attenuation
enables studio quality video playback on modern TVs, giving
optimal horizontal line resolution. An additional sharpness
control feature allows high-frequency enhancement on the lumi-
nance signal.
