FPGA Configuration Data Source Jumper

Jumper JB9 selects the source of the Virtex FPGA configuration data down−
load. The FPGA can select its configuration data either from an on−board
Serial EEPROM or from a serial download (X−Checker cable), depending on
the setting of this jumper. The following table shows the jumper settings for
this FPGA configuration data source jumper. This jumper block has three
pins, similar to the Filter Bypass jumpers (see illustration in
prior page). (Refer to Virtex Config Register,
mation on reconfiguring the Virtex FPGAs.)

External TTL Inputs Select Jumpers

Jumper block JB10 selects the input connector to use as the source of the
external TTL SYNC or TTL GATE inputs. Each TTL signal can be input from
either the 26−pin sync/gate connector (see
gate header (see Section
the jumper settings for this jumper block.
