1Introduction
1.1 Description
The VAMP-XGA3 is a standalone, LCD-based multi-sync video digitizer for LCD-based
applications. The VAMP-XGA3 incorporates the components necessary to digitize analog RGB,
VGA, SVGA and XGA, as well as SOG, NTSC and Composite video input signals. Video
processing includes input video digitizing and frame rate conversions, video scaling from low
resolution inputs to higher resolution LCD panels, and output timing and control to maintain a set
output frame rate required by the LCD target panel.
An on-board micro-controller functions as the main system controller, responsible for
system initialization, On Screen Display (OSD) user interface, input mode auto-detection, and
other housekeeping functions.

•Accepts analog RGB inputs up to 1024 x 768 at 85Hz. Refer to Table 10 : RGB Input Signal
Description
•Accepts NTSC and Sync-on-Green or Composite inputs.
•Supports Frame Rate Conversion for over 20 different input formats.
•Drives 1024x768 LCD panels at 60 Hz frame rates via an LVDS interface. (The LCD backlight is
controlled via a separate connector.)
•Remote keypad connector allows the user to sequence through on-screen menus, allowing
adjustments to the system.
1.2 VAMP-XGA3 Power Supply Requirements
An SH34 panel was used for these measurements. The total power of 18.5W (1.54A)
should be considered the minimum requirement. If the board will be supplying power to other
system devices the external power requirements plus margin should be added to this total.

2.6 Auxiliary Power Interface (J2 and J6)
The auxiliary power connectors, J2 and J6, are straight 4x1 locking headers with 0.1"
centers. They are used to supply power to other parts of the system. Do not connect power for
the VAMP-XGA3 to J2 or J6. Both connectors have the same pinout as the DP-POW-DIS board.

2.7 LED Indicators
PWR LED "on" steady, indicates that power is good and the VAMP-XGA3 is functioning
normally. PWR LED blinking rapidly indicates that a fatal error has occurred. PWR may blink
slowly during power up and video mode changes. This is normal.
The VIDEO LED is a video sync indicator. If syncs are detected when an active video
source or PC Graphics source is connected, the VIDEO LED will be on. A blue screen should
appear on the display when the VAMP-XGA3 is powered up and syncs are not detected (VIDEO
LED is OFF).

3.1 User Interface Overview
An external switch box interface (J11) to the micro-controller accepts user selections in
response to OSD Input Selection and Display Control menu options. The external switch box
layout is shown in Figure 3-1. External Switch Box Layout, below. On-board firmware monitors
switch activity and responds accordingly. The OSD menus provide the user with visual
confirmation of selections and adjustments by highlighting selections and modifying on-screen
bar-graph levels.
