The FMC DIO 10I8O has 10 inputs on which it will be possible to set two bipolar references using 2 comparators (LMH7324 model) per input. The hysteresis has been added with a feedback.
The references are set using DAC (7716 model), communicated through
SPI-daisy chain.
Termination input is selectable through I2C from the FMC.
There are 8 monitored outputs using an octal line driver (sn74bct25244).
Communication from the comparators outputs and the FPGA uses LVDS.
LVDS signals are also used to activate the line driver outputs through a
LVDS receiver.
Input voltages: +-5V.
I/O on FMC connector side: compatible with 1.8 and 2.5V
This board is designed primarily to deal with the pick-up and trigger signals that can be found in the TE-ABT-EC environment, which is dedicated to the controls of the kicker magnets.
All comments are more than welcome.
