2.Why we do this?Development of first prototype for proof-of-concept evaluation
3. Our Resources for this board:Original ICECAL_V2 Test-Board schematics • I’ve been in contact with ICECAL’s main designers: Eduardo Picatoste & David Gascón• ICECAL is a serious candidate to our system since is the natural evolution of the Readout ASIC we´re using now in the surface.• The designers kindly provided 2 x ICECAL_V2 samples, schematics of their test board and many useful advices. (Thanks guys!)• Version 2 1 Channel, no multiplexer, no I_Bias Cirquits, no ADC Driver, no Delay line, but useful for our prototype.• Version 3 4 Channels with everything included (Smaller test board needed). Soon under evaluation.
• The task I’m carrying out: I’ll modify their test board to our needs.
• Lars also provided the schematics of his VTRX adapter module (Custom SFP-HSMC Adapter Board) https://indico.cern.ch/event/284352/
