Table 1. PIN DESCRIPTIONS
Pin(s)
Name
Description
1
V_CC3
V_CC3 supply pin. This is an isolated supply input for the two sync buffers and SD1 and SD2 ESD
protection circuits.
2
V_CC1
V_CC1 supply pin. This is an isolated supply pin for the VIDEO_1, VIDEO_2 and VIDEO_3 ESD
protection circuits.
3
VIDEO_1 Video signal ESD protection channel. This pin is typically tied one of the video lines between the VGA
controller device and the video connector.
4
VIDEO_2 Video signal ESD protection channel. This pin is typically tied one of the video lines between the VGA
controller device and the video connector.
5
VIDEO_3 Video signal ESD protection channel. This pin is typically tied one of the video lines between the VGA
controller device and the video connector.
6
GND
Ground reference supply pin.
7
PWR_UP Enables the sync buffers when high. When PWR_UP is low the sync outputs are forced low and the
inputs can be floated.
8
V_CC2
V_CC2 supply pin. This is an isolated supply pin for the DDC_OUT1 and DDC_OUT2 ESD protection
circuits. Internally, V_CC2 is derived from the V_CC3 input if the V_CC2 input is not connected to a supply
voltage.
9
DDC_OUT1 DDC_OUT1 ESD protection channel.
10
DDC_OUT2 DDC_OUT2 ESD protection channel.
11
SYNC_IN1 Sync signal buffer input. Connects to the VGA Controller side of one of the sync lines.
12
SYNC_OUT1 Sync signal buffer output. Connects to the video connector side of one of the sync lines.
13
SYNC_IN2 Sync signal buffer input. Connects to the VGA Controller side of one of the sync lines.
14
SYNC_OUT2 Sync signal buffer output. Connects to the video connector side of one of the sync lines.
15
SD1
ESD protection channel input.
16
SD2
ESD protection channel input.
