A same board can satisfy all the requirements for data transmission, timing and fast control as well as slow control. First developments rely on a generic ATCA carrier board equipped with four dense AMC mezzanine able to interface a total of 144 bidirectional optical links at up to 10 Gbits/s. Early results and measurements will be presented. Talk LHCb Readout CERN Upgrade CERN CERN LHCbTALK 1459551 oxford20120917 PUBLIC LHCbCERNTALK
