The readout chip for the CMS pixel detector must handle an enormous flux of data, while keeping the data loss at a minimum. Full size prototype readout chips bump-bonded to sensors have been tested in a pion beam simulating an LHC-like environment, and the data loss as a function of particle fluence has been measured.
