8.3. Digital Video Out Port
The GMCH DVO port interface supports a wide variety of third party DVO compliant devices (e.g. TV
encoder, TMDS transmitter or integrated TV encoder and TMDS transmitter The Intel 852GM has a
single dedicated Digital Video Out Port (DVOC). Intel’s DVO port is a 1.5-V only interface that can
support transactions up to 165 MHz. Some of the DVO port command signals may require voltage
translation circuit depending on the third party device.
