Prototyping Area; Vcco-Enable Supply Jumpers; Vbatt - Xilinx Virtex-5 LXT User Manual

Detailed Description
6d. Downstream Interface Connector
The downstream interface connector (P4) passes serial configuration information to the
DUT in the downstream prototype platform board
X-Ref Target - Figure 8

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-5 FPGAs have 9 to 33 SelectIO banks (J44 and J45), labeled VCCO_0 to VCCO_34,
each with a V
each bank to one of the two onboard supplies, the V
must be installed for the Virtex-5 device to function normally.

9. VBATT

An onboard battery holder (B1) is connected to the VBATT pin of the DUT. If an external
power supply is used, the associated jumper must be removed; instead, use a 12-mm
lithium coin battery (3V).
