KC724 GTX Transceiver Characterization Board
UG932 (v2.2) October 10, 2014
Chapter 1:
KC724 Board Features and Operation
The JTAG chain of the board is illustrated in
. By default only the Kintex-7
FPGA and the System ACE SD controller are part of the chain (J1 jumper OFF). Installing
the J1 jumper adds the FMC interfaces as well.
PROG_B Push Button
Pressing the PROG push button SW3 (callout
) grounds the active-Low
program pin of the FPGA.
DONE LED
The DONE LED DS21 (callout
,
) indicates the state of the DONE pin of the
FPGA. When the DONE pin is High, DS21 lights indicating the FPGA is successfully
configured.
