The IFR Crate Controller ( ICC ) is the board
responsible to collect IFR data from IFB, ICB and ITB and to trasmit it
to the ROM using the G_link.
It doesn't perform any test on the data, it acts only as a multiplexing
( demultiplexing ) of data and commands. ICC is also responsible to distribute
the clock to others boards and to reformat the clock used to send back the data
to ROM.
Another important task of ICC is the monitor of the FE crate; it read the
voltage and current of power supply and it monitor also the temperature
inside the crate reading the value of 7 sensor ( AD592 ). All these information
are transmitted to the detector control crate via the CAN Bus.
