Power and Power-On Sequence
Power Supply
Single 3.3V power supply (for both VIN and 3.3VIN power rails) with minimum current capability of 3A for
system startup is recommended.
Power Consumption
Typical module power consumption is between 2-3W. Exact power consumption is to be determined.
TE0712-02 module can also be powered by split 5V/3.3V power sources if preferred. In such case apply 5V
to B2B connectors VIN pins and 3.3V to 3.3VIN pins, although lowest power consumption is achieved when
powering the module from single 3.3V supply. When using split 5V/3.3V supplies the power consumption
(and heat dissipation) will rise due to the DC-DC converter efficiency (it decreases when VIN/VOUT ratio
rises).
Power-On Sequence
For the highest efficiency of the on-board DC-DC regulators, it is recommended to use same 3.3V power
source for both VIN and 3.3VIN power rails. Although VIN and 3.3VIN can be powered up in any order, it is
recommended to power them up simultaneously.
It is important that all baseboard I/Os are 3-stated at power-on until System Controller sets PGOOD signal
high (B2B connector JM1, pin 30), or 3.3V is present on B2B connector JM2 pins 10 and 12, meaning that
all on-module voltages have become stable and module is properly powered up.
See Xilinx datasheet DS181 - "Artix-7 FPGAs Data Sheet: DC and AC Switching Characteristics" for
additional information. User should also check related baseboard documentation when choosing baseboard
design for TE0712 module.
