AGP-Multiplexed Digital Video Port 1 (GDVP1) – TV Encoder
The above pins may be connected to an external TV Encoder chip such as a VIA VT1623 or
VT1623M for driving a TV set.
I/O pads for the pins on this page are powered by VCC15AGP (1.5V I/O).
Note: If the FPD port is enabled and TV-out capability is required at the same time, the
dedicated TV-out port (DVP0) must be used because pin AG1 will be dedicated to the FPDET
function.
