Abstract :
A 16-channel digital TDC chip has been built for the DIRC Cerenkov counter of the BaBar experiment at the SLAC B-factory (Stanford, USA). The binning is 0.5 ns and the full-scale 32 microseconds. The data driven architecture integrates channel buffering and selective readout of data falling within a programmable time window. The linearity is better than 80 ps rms on 90% of the production parts
