UG027 / PN 0402044 (v1.6) October 25, 2002
1-800-255-7778
Detailed Description
R
The voltage regulators deliver fixed voltages. Maximum current range for each supply is
2A.
Table 1-1
shows the maximum voltage for each power supply jack.
Note:
To power the V
CCAUX
pins you must jumper the pins labeled VAUX enable located next to
the VCCAUX jack on the board. This action will connect the V
CCAUX
pins on the DUT to V
CCO
.
Off Position
In the off position, the power switch disables all modes of powering the DUT.
Power Enable Jumpers
For each power supply there are headers marked
Supply
on one side and
Jack
on the other
side. Appropriate placements of jumpers on these headers enables delivery of all power
from either the onboard regulators or the four power supply jacks marked
VCORE
,
VCCO
,
VCCAUX
, and
MGT_VCC
.
2. Power Supply Jacks
One method of delivering power to the DUT is by way of the power supply jacks. (Consult
the Xilinx data book,
http://www.xilinx.com/partinfo/databook.htm
, for the maximum
voltage rating for each device you are using.) The power supply jacks are:
•
VCORE
♦
Supplies voltage to the core of the DUT
•
VCCO
♦
Supplies I/O voltages to the DUT
♦
Each bank can be powered from one of two sources (V
CCO
, V
CCINT
) by
appropriate placement of jumpers on the header
•
VCCAUX
♦
Supplies voltage to the V
AUX
header and the V
AUX
DUT pins
•
MGT_VCC
♦
Supplies power to the Rocket I/O transceivers on the DUT (AV
CC
AUX, VTT
X
,
VTR
X
)
