DKHiQV-AGP (Fab. Rev. A) Subject to Change Without Notice
Revision 1.0 7/13/98
3.8.2
Clean 3.3V Power for the
3DQHO/LQN
Transmitter
JP4 allows 3.3V to be supplied to the
3DQHO/LQN
transmitter and receiver cards from the 3V regulator U13
(Voltage adjusted by R75). JP4 also allows 5V to be used instead for other types of interfaces such as 5V
LVDS. For
3DQHO/LQN
operation, only the
3DQHO/LQN
transmitter and receiver cards should be powered
from this regulator (via JP4), and the voltage should be set to 3.3V (within 5%). In addition, the DVCC55X
voltage should also be set for 3.3V, from U15 via W35 and W30. Any other 3.3V voltages used in the system
(except for the
3DQHO/LQN
interface) should also come from the U15 regulator. The reason for separating
the
3DQHO/LQN
voltage from the other loads is to provide a very clean 3.3V source to the
3DQHO/LQN
chips.
This is most important at XGA frequencies (65 MHz).

Installation Procedures
1.
Unpack the DKHiQV-AGP (Fab Rev. A) board and visually inspect for any damage that may have
occurred during shipping.
2.
Read this DKHiQV-AGP (Fab Rev. A) User’s Guide to become familiar with the board operations.
3.
Read the ABHiQV (Fab. Rev. B) daughtercard User’s Guide and schematics to become familiar
with board operations.
4.
Read the MM6555x (Fab. Rev. B) Multimedia Daughtercard User’s Guide to become familiar with
board operations.
5.
Check that all jumpers are in their default positions as shown in Tables 8 through 11. Refer to Fig-
ures 1 and 2 for jumper locations.
Note: For TV out and multimedia settings, refer to Tables 12 and 13.
6.
Plug the ABHiQV (Fab Rev. B) daughtercard onto the DKHiQV-AGP board. The connectors/head-
er in the ABHiQV daughtercard is composed of eight 2X16 header-socket-type pins (P1).
7.
Power down the host system and plug the DKHiQV-AGP board into an available AGP slot on the
motherboard.
Please note that the DK-HiQV-AGP board does not plug into ISA, VL-bus or PCI-bus.
8.
Connect the monitor to the 15-pin VGA connector. The default configuration of the DK board is for
CRT display.
9.
Turn on the system power and observe the sign-on message. The sign-on message does not ap-
pear, turn off the system power and follow the instructions in the troubleshooting section of this Us-
er’s Guide.
10.
Load the proper driver, BIOS and utilities to activate the ABHiQV daughtercard.

HiQVideo Utilities and Drivers
The SETCLK utility included in the utilities diskette independently programs MCLK and DCLK of the HiQVid-
eo
controller. The diskette also provides other utilities such as MODETEST. The MODETEST utility runs
through all the standard VGA modes and super VGA modes. The driver diskettes also contain high perfor-
mance display drivers for Windows95. WindowsNT drivers (and other files and utilities) are available on our
BBS (bbs.chips.com) for your use. The diskette also contains text files to help you install these drivers.
