• Generic connectors waiting for final specifications : use of adaptor mezzanines
• Large number of I/O for flexibility
• Various I/O format : LVDS, LVCMOS, NIM, Analog (10b, 40 MHz, ADC included)
• USB for slow control and read-out
• Connector for options : LDAitf, ethernet, debug, …

Cooperation between LPC-Clermont & Tsinghua
Univ. Expertise
• LPC-Clermont - 10 bits ADC already realized - Support from electronics team - Involves in CALICE Collaboration - RAQ is starting on prototype schematics
• Tsinghua Univ. - LHCb DAQ and commission - Trigger system for DaYaBay Experiment
13
Conclusion• Front-End-Electronics is crucial and very
challenging for ILC Calorimeter development
• LPC-Clermont & Tsinghua Univ. would like to team up under FCPPL support to work on the R&D of FEE for ILC Calorimeter.
Thank You !
