RF and SiliconPhotonics Radiation-Hard Circuits for High-Speed Links in Aerospace and High Energy Physics Applications
telecommunications, remote sensing and science missions, leads to an increased frequency and
data-rate requirements for on-board equipments, as recently demonstrated by the publication
of the Spacefiber standard by ESA, May 2019.
The Spacefiber technology aims at a data-rate of 6.25 Gbps for each link, replacing the previous Spacewire standard, which was sized for data-rates of hundreds of Mbps. Spacefiber sustains both electric and optical physical layers. In High Energy Physics applications, the target data rates may be even higher

in close collaboration with other institutes like INFN, CERN, IMEC we are developing all the integrated building blocks able to face harsh aerospace environments in both RF silicon and silicon-photonics technologies to create a high-speed bridge between the electronic world and the photonic one: Ring-resonator and Mach Zehnder optical modulators, High-speed drivers, Phase Locked Loops and Voltage Controlled Oscillators for clock generation and clock data recovery, SerDes.
The technology is currently being covered by patents from University of Pisa and INFN.
The designed blocks are able to sustain high data-rates (10 Gbps in 65nm technology node, 25 Gbps in 28 nm) being robust to single event effects and total ionization dose.
The blocks are available both as integrated devices to be assembled on electronic boards or hard macro IP cores to be integrated in System-on-Chip solutions.
