Multi-gigabit low-power radiation-tolerant data links and improved data motion in trackers

Abstract

We present a set of links based on data-transmission IP in 130nm designed for rapid integration into ASIC designs. These links are designed for use in very high radiation environments as occur in high energy physics experiments. The designs are additionally low power and small area, easing integration with other electronic systems. These links are well suited to use in tracking detectors. Trackers, due to their close proximity to the collision, are subject to very high levels of radiation, and hence require such radiation hardened electronics. The portfolio of radiation hardened data transmission blocks consists of a 1Gbps serializer/deserializer with a very low power consumption ~1mW for each. A differential transmitter and differential receiver rated at 3GHz, both designed to be much faster than needed, as insurance against radiation damage. Finally, the impact of a prototype low-latency, low-power ( < 60mW total link power) 5Gbps link is considered. Case analysis of the impacts of using lower powered, higher speed blocks in hypothetical trackers is studied, showing power improvements relative to alternative technologies.
