Implementation of a sub 10ps RMS jitter TDC in Xilinx 7-series FPGAs — •Verena Leopold1, Yury Prokazov2, Evgeny Turbin2, Stefan Richter1, and Joachim von Zanthier11FAU, Erlangen, Germany — 2Photonscore, Magdeburg, Germany

For many experiments in quantum optics, it is crucial to detect photon arrival times from (multiple) detectors. Usually a TDC (Time-to-Digital-Converter) is used for recording of this time stream. However for low-contrast, long-running measurements, available TDCs show disadvantages. The main challenges are high quality analog inputs and non-linearities on short ps-timescales. We successfully implemented a TDL (Tapped-Delay-Line) TDC inside an FPGA. Communication with the CPU is established by PCIe. Using Xilinx 7-series silicon, a RMS jitter of (3.24 ± 0.03) ps was obtained with non-linearities in the regime of 0.32%.
