3 Hardware Configuration
In this section, the various portions of the TSW14J10EVM hardware are described. The TSW14J10EVM
comes with a 10 pin ribbon cable that is used as a programming option for the FPGA on the FPGA
Development Board, plastic screws and nuts to secure the three boards together, and stand-off extenders
to be used on the ADC/DAC EVM due to the new height of the interface FMC connector.
3.1 Power Connections
The TSW14J10EVM hardware is designed to operate from a single-supply voltage of +5 VDC. By default,
this power input is provided by the USB connection. A second option is to provide ex5 V to test
point TP12 and shunt pins 1-2 on JP1. This will remove the USB power from the +5-V power traces and
connect it to TP12. The external source should be able to provided 0.5 A.
3.2 Jumpers
The TSW14J10 contains several jumpers (JP) and solder jumpers (SJP) that enable certain functions on
the board. The description of the jumpers are found in
Table 1 . In addition to the jumpers, there are
several 0 Ohm resistors that are used as jumpers. If using the TSW14J10EVM with the Xilinx ZC706 and
a TI DAC EVM, the following resistors need to be removed or installed to route the SYNC signals from the
DAC EVM to the correct pins on the ZC706 board:
Install R142, R144, R146 and R148
Remove R143 and R145
