Detailed Description
R
6d. Downstream Interface Connector
The downstream interface connector, as shown in Figure 7, passes serial configuration
information to the DUT in the downstream prototype platform board.
7. Prototyping Area
The prototyping area accommodates 0.10-inch spaced ICs. The kit contains headers that
can be soldered to the breakout area, if desired. Power and ground buses are located at the
top and bottom edges, respectively, of the prototyping area.
8. VCCO-Enable Supply Jumpers
Virtex-4 series devices have 9 to 17 SelectIO banks, labeled 0 through 16, each with a
VCCO-enable supply jumper. The VCCO-enable supply jumpers can connect each bank to
one of the two onboard supplies, VCCINT or the VCCO supply. These jumpers must be
installed for the Virtex-4 device to function normally.
9. VBATT
An onboard battery holder is connected to the VBATT pin of the DUT. If an external power
supply is used, the associated jumper must be removed and instead use a 12 mm lithium
coin battery (3V).
