Abstract
We have developed a high-performance time digitizer system using a supercon ductor technology for high-energy and nuclear physics detector instrumentat ion, CMOS chip diagnostics, and military applications. The system consists of an 8-channel, RSFQ multi-hit Time-to-Digital Converter (TDC) integrated into a single system with a semiconductor VXI interface and control modules . The Digitizer operation and output digital data analysis are performed an d fully controlled using custom PC-based LabVIEW (TM) software. This all-di gital TDC contains eight 9-bit, 14-bit, 20-GHz TDC channels on a 1 cm x 1 c m chip. The TDC chip is capable of operation in Common Start and Common Sto p modes. The VXI digitizer part comprises a 200 MS/s, 8-channel data receiv er module, a TDC control module, and a commercial VXI-PCI link The data rec eiver module converts data into ECL format. The TDC control module based on Xilinx CPLD technology sorts this data and also controls the superconducti ve RSFQ chip operation by producing all necessary control and readout signa ls. We present results of operation and experimental performance evaluation of this system.
