DESCRIPTION
Horizontal sync signal buffer output. Connects to the video connector side of the horizontal sync
line.
Horizontal sync signal buffer input. Connects to the VGA Controller side of the horizontal sync
line.
Digital ground reference supply pin.
V
Blue signal video protection channel. This pin is typically tied to the B video line between the
VGA controller device and the video connector.
Green signal video protection channel. This pin is typically tied to the G video line between the
VGA controller device and the video connector.
Red signal video protection channel. This pin is typically tied to the R video line between the
VGA controller device and the video connector.
Analog ground reference supply pin.

and ESD protection circuits. It is also connected to the sync buffers and to the ESD protection
diodes present on the HSYNC_OUT and VSYNC_OUT lines.
DDC data pin.
DDC clock pin.
V
VSYNC buffer inputs.
Vertical sync signal buffer input. Connects to the VGA Controller side of the vertical sync line.
Vertical sync signal buffer output. Connects to the video connector side of the vertical sync line.
