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)
