DESCRIPTION
Positive voltage supply pin. This is an isolated V
and SD2 circuits.
Positive voltage supply pin. This is an isolated V
VIDEO_3 ESD circuits.
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.
Digital Ground reference supply pin.
Ground reference supply pin for TERM_1, TERM_2 and TERM_3 pins.
RGB Video Termination Channels. These pins tie to the RGB video lines (for example,
the Blue signal) providing a 75Ω termination to GNDA for the given video channel.
Sync Signal Output 1. Ties to the video connector side of one of the sync lines (for
example the Horizontal Sync signal).
Positive voltage supply pin. This is an isolated V
input circuits. Defines the logic one level for the DDC_OUTn outputs.
Used to derive V
Positive voltage supply pin. This is an isolated V
DDC_OUT2 ESD protection circuits.
DDC Signal Output 1. Connects to the connector side of one of the DDC signals (for
example, the bidirectional DDC_Data serial line).
DDC Signal Input 1. Connects to the VGA Controller side of one of the DDC signals (for
example, the bidirectional DDC_Data serial line).
DDC Signal Input 2. Connects to the VGA Controller side of one of the DDC signals (for
example, the bidirectional DDC_Clk).
DDC Signal Output 2. Connects to the connector side of one of the DDC signals (for
example, the bidirectional DDC_Clk).
Sync Signal Buffer Input 1. Connects to the VGA Controller side of one of the sync lines
(for example, the Horizontal Sync signal).
Sync Signal Buffer Output 1. Connects to the video connector side of one of the sync
lines (for example the Horizontal Sync signal).
Sync Signal Buffer Input 2. Connects to the VGA Controller side of one of the sync lines
(for example, the Vertical Sync signal).
Sync Signal Buffer Output 2. Connects to the video connector side of one of the sync
lines (for example the Vertical Sync signal).
Sync Signal Filter 1. Connects to the video connector side of one of the sync lines (for
example the Vertical Sync signal).
Sync Signal Filter 2. Connects to the video connector side of one of the sync lines (for
example the Horizontal Sync signal).
