Abstract :
Gbit/s data transmission links will be used in several LHC detectors in trigger and data acquisition systems. In these experiments, the transmitters will be subject to high radiation doses over the lifetime of the experiments. In this work, a radiation tolerant transmitter ASIC is described. The IC supports two standard protocols, the G-link and the Gbit-Ethernet, and sustains transmission of data at both 800 Mbit/s and 1.6 Gbit/s. The ASIC was implemented in a mainstream 0.25 μm CMOS technology employing radiation tolerant layout practices. A 1.2 Gbit/s prototype with reduced functionality was tested. The ASIC behavior under total dose irradiation as well as its susceptibility to single event upsets was studied and the results are reported here
