Abstract	The electronics for the electromagnetic and hadronic calorimeters of LHCb is under design. The 32 channel-9U front-end board offers the complete front-end and readout electronics for every channel including original shaping, 12bit-40MHz ADC, digital filtering and latency for level 0 and level 1 triggers. The clipped PM input signal is integrated during 25ns, but also delayed then subtracted to itself 25ns later which allows performant pile up independence. This board also includes the first processing levels of the L0 calorimeter trigger. A 16 channel-6U prototype board has been designed and used at CERN in test beam in 1999.
