SLAC Ultimate Gateway Operational Interface (SUGOI) Protocol for Fiber Optic ASIC/FPGA Communication

It has become common practice for High Energy Physics (HEP) experiments to design their data acquisition systems such that the sensor ASIC and controller FPGA are no longer on the same board or even in the same room. Cabling lengths between the FPGA and ASIC becoming 100+ meters makes fiber optic communication necessary to remove grounding loops and noise pick up. We will present a serial communication protocol targeted for handling the requirements that HEP experiments typically impose on the ASIC design (e.g timing synchronization, register access, etc).
