We report the design, operation, and performance of a next generationhigh-speed data acquisition system for multi-channel infrared and opticalphotometry based on the modern technologies of Field Programmable Gate Arrays,the Peripheral Component Interconnect bus, and the Global Positioning System.This system allows either direct recording of photon arrival times or binnedphoton counting with time resolution up to 1-$\mu$s precision in UniversalTime, as well as real-time data monitoring and analysis. The system also allowssimultaneous recording of multi-channel observations with very flexible,reconfigurable observational modes. We present successful 20-$\mu$s resolutionsimultaneous observations of the Crab Nebula Pulsar in the infrared (H-band)and optical (V-band) wavebands obtained with this system and 100-$\mu$sresolution V-band observations of the dwarf nova IY Uma with the 5-m Haletelescope at the Palomar Observatory.Comment: 11 pages, including 4 figures, to appear in PAS
