DESCRIPTION
This is an isolated supply input for the SYNC_1 and SYNC_2 level shifters and their
associated ESD protection circuits.
This is a supply pin specifically for the VIDEO_1, VIDEO_2 and VIDEO_3 ESD protection
circuits.
Video signal ESD protection channel. This pin is typically tied one of the video lines
between the VGA controller device and the video connector.
Ground.
This is an isolated supply input for the DDC_1 and DDC_2 level-shifting N-FET gates.
This input is Using a 0.2uF bypass capacitor will increase the ESD robustness of the
system.
DDC signal output. Connects to the video connector side of one of the sync lines
