The basic idea behind this board is to have a FPGA board that interface a VME connector compatible with the POETIC Rack backplane. This board was developped during Jean Nanchen's TB (2021) and used in the NGRW project in addition with the FPGA ADC-DAC Mezzanine.

Analog to digital converters
The mezzanine board holds 20 ADS7886 analog to digital converters.
These are 12 bit converters with a maximal sampling rate of 1 MHz.
Actually Channel 6, 7, 8, 9, 10, 12, 13, 14 and 15 don't work (Probably due to propagation delay with SCLK)
Digital to analog converters
The mezzanine board holds 2 DAC124S085 quad analog to digital converters, allowing for 8 analog output channels.
These are quad 12 bit converters with a maximal sampling rate of 1.8 MHz if only one channel is used. The sampling rate drops to 460 kHz when all 4 channels are used.
Programmation
V1.0 is only programmable via JTAG.
