GENERAL DESCRIPTION
The ADV7172/ADV7173 is an integrated Digital Video En-
coder that converts digital CCIR-601 4:2:2 8-bit component
video data into a standard analog baseband television signal
compatible with world wide standards.
There are six DACs available on the ADV7172/ADV7173. In
addition to the Composite output signal there is the facility to
output S-VHS Y/C Video, RGB Video and YUV Video.
The on-board SSAF (Super Sub-Alias 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 extra luminance boost on the frequency
response.
An advanced power management circuit enables optimal control
of power consumption in both normal operating modes and
power down or sleep modes. A PC’98-Compliant autodetect
feature has been added to allow the user to determine whether
or not the DACs are correctly terminated. If not, the ADV7172/
ADV7173 flags that they are not connected through the Status
bit and provides the option of automatically powering them
down, thereby reducing power consumption.
