Abstract :
A new TDC LSI and a TDC VME module have been developed. The TDC LSI (called AMT-2) will be used in muon precision trackers of the ATLAS experiment. The AMT-2 chip has 24 input channels and 280 ps RMS resolution. It is processed in a 0.3 μm CMOS technology. The TDC module (called AMT-VME) has 64 channels and has wide timing range (∼100 μsec) with a 0.78 ns/bit timing resolution. The module also contains a DSP for controlling data acquisition and manipulating data. Acquired data are read out via VME bus through a dual port memory. Designs of the chip and the module are presented, and preliminary test result is shown.
