PIN DESCRIPTIONS
LEAD(s)
1
NAME
V_CC4
DESCRIPTION
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, RGB Video Protection Channels. These pins tie to the RGB video lines (for example,
VIDEO_3
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, RGB Video Termination Channels. These pins tie to the RGB video lines (for example,
TERM_3
the Blue signal) providing a 75Ω 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 from V input.
CC3
CC4
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).
