Abstract

A custom, multi-stage, FPGA-based testing platform is proposed for signal integrity testing of superconducting interonnects at gigabit-speeds (6 Gb/s) with emulated, amplified single flux quantum (SFQ) pulses at cryogenic temperatures (4 K). Results for superconducting Nb-striplines will be shown utilizing this platform and characterization for the cryogenic performance of the FPGA's transceivers will be shown. Performance and implementation results demonstrate the viability of complex, CMOS technologies at cryogenic temperatures, providing scalable control and readout options for superconductor-based technologies.
