ADV7172:  Digital PAL/NTSC Video Encoder with Six DACs (10 Bits), Color Control, Power Management, Macrovision 7.01

Product Description

The ADV7172/ADV7173 is an integrated Digital Video Encoder that converts digital CCIR-601 4:2:2 8-bit component video data into a standard analog baseband television signal compatible with worldwide 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.

The ADV7172/ADV7173 also supports both PAL and NTSC square pixel operation. The parts also incorporate WSS and CGMS-A data control generation.

Applications

  • High Performance DVD Playback Systems, Portable Video Equipment including Digital Still Cameras and Laptop PCs, Video Games, PC Video/Multimedia and Digital Satellite/Cable Systems (Set-Top Boxes/IRD)
