Lead(s)
Name
Description
1
V_CC4
Positive voltage supply pin. This is an isolated V_CC pin for the SYNC_1, SYNC_2, SD1
and SD2 circuits.
2
V_CC1
Positive voltage supply pin. This is an isolated V_CC pin for the VIDEO_1, VIDEO_2
and VIDEO_3 ESD circuits.
3−5 VIDEO_1, VIDEO_2, VIDEO_3 RGB Video Protection Channels. These pins tie to the RGB video lines (for example,
the Blue signal) between the VGA controller device and the video connector.
6
GNDD
Digital Ground reference supply pin.
7
GNDA
Ground reference supply pin for TERM_1, TERM_2 and TERM_3 pins.
8−10
TERM_1, TERM_2, TERM_3 RGB Video Termination Channels. These pins tie to the RGB video lines (for example,
the Blue signal) providing a 75 W termination to GNDA for the given video channel.
11
PWR_UP
Sync Signal Output 1. Ties to the video connector side of one of the sync lines
(for example the Horizontal Sync signal).
12
V_CC2
Positive voltage supply pin. This is an isolated V_CC pin for the DDC_IN1 and DDC_IN2
input circuits. Defines the logic one level for the DDC_OUTn outputs.
13
V_BIAS
Used to derive V_CC3 from V_CC4 input.
14
V_CC3
Positive voltage supply pin. This is an isolated V_CC pin for the DDC_OUT1
and DDC_OUT2 ESD protection circuits.
15
DDC_OUT1
DDC Signal Output 1. Connects to the connector side of one of the DDC signals
(for example, the bidirectional DDC_Data serial line).
16
DDC_IN1
DDC Signal Input 1. Connects to the VGA Controller side of one of the DDC signals
(for example, the bidirectional DDC_Data serial line).
17
DDC_IN2
DDC Signal Input 2. Connects to the VGA Controller side of one of the DDC signals
(for example, the bidirectional DDC_Clk).
18
DDC_OUT2
DDC Signal Output 2. Connects to the connector side of one of the DDC signals
(for example, the bidirectional DDC_Clk).
19
SYNC_IN1
Sync Signal Buffer Input 1. Connects to the VGA Controller side of one of the sync lines
(for example, the Horizontal Sync signal).
20
SYNC_OUT1
Sync Signal Buffer Output 1. Connects to the video connector side of one of the sync lines
(for example the Horizontal Sync signal).
21
SYNC_IN2
Sync Signal Buffer Input 2. Connects to the VGA Controller side of one of the sync lines
(for example, the Vertical Sync signal).
22
SYNC_OUT2
Sync Signal Buffer Output 2. Connects to the video connector side of one of the sync lines
(for example the Vertical Sync signal).
23
SD1
Sync Signal Filter 1. Connects to the video connector side of one of the sync lines
(for example the Vertical Sync signal).
24
SD2
Sync Signal Filter 2. Connects to the video connector side of one of the sync lines
(for example the Horizontal Sync signal).
