Power Supply Module 1.1 and 1.2 for Series 1 FPGA Boards
Series 1 FPGA Boards are deprecated. Please switch to Series 2.
An Adapter is available as workaround.
The old product page is still available here for documentation purposes.
The following drawing shows the measurements and the location of the of the described elements.
External power: CON1 and CON2CON1 is a standard DC power jack with 2.1mm center pin diameter for a supply voltage of 4.5 V to 16 V. The DC connector delivered with the Power Supply Module can be installed on both sides.
Alternatively CON2 can be used to connect non standard power cables. The ground pin of CON2 (round pad) is marked with "-" and the supply pin (quadratic pad) is marked with "+", see the images below. The connector set delivered with the board can be installed on both sides.
If non-stabilized power supplies are used it must be made sure that the peak voltage is not larger then 18V.
Hints for power supply via USB can be found on the ZTEX Wiki.
JTAG connector: CON4, CON3The Power Supply Module contains two JTAG connectors. CON3 is a 14 pin, 2.0mm pitch connector standardized by Xilinx. installed on the bottom side.
CON4 can be used to connect non-standard JTAG programmers. If used, the pin header delivered with the board has to be
The pin descriptions can be found in the silk screen (see the images).
The voltage for the I/O signals (TCK,TMS,TDI,TDO) is 2.6V. The supply pin of this voltage is labelled with "VIO". The "3V3" pin to CON7 can be used as 3.3V supply for the JTAG adapter.
I/O voltages: JP1Jumper JP1 sets the I/O VCCO_IO(=VCCO_RIGHT) and VCCO_TOP, respectively. A pin header is delivered with the board and can be installed on both sides.
By closing this jumpers (see images below) the I/O voltages can be switched easily to 3.3V, 2.6V or 1.2V. If other I/O voltages are required the jumpers must be left open and the I/O voltage must be supplied via the pins of the I/O Connector.
