Hardware/FPGARackZynqADDAV1
From UIT
|
This board embeds 4 ADCs, 4 DACs and a FPGA/CPU kit. It is intended to be used for data acquisition / generation / processing. Unlike the OLGMADDA V1 board or the HiSADDA V1 board, the FPGA includes a hard-core ARM CPU (useful with a Linux and Ethernet, for example). This board was developped by pah (Charles Papon) for his master thesis.

Power supply considerations
This board is powered through the HVME backplane bus (+5V, +12V, -12V).
VME connector logic levels
The I/O bank which interfaces the VME connector is only 3.3V. Be careful with other FPGA Rack boards with 2.5V/3.3V jumper.
Known issues
The following points need to be considered when using this board version :
- Inverted polarity on DAC outputs.
- On the TE0720 kit, the thermal dissipation is too big for the passive heatsink. An additionnal fan is required.
- On the user I/O of the TE0720 kit, pin MIO0 must be overridden to GND due to a Xilinx tools issue with the microSD card detection.
- Bad labeling on the PCB :
- Swapped "ADx" and "DAx" labels
- Swapped CH0-CH1 for the DAC.
- Swapped CH2-CH3 for the DAC.
- All testpoints (power supplies + GND) are unconnected (PCB layout issue).
