The Sudbury Neutrino Observatory (SNO) is a second generation real time solar neutrino water Cherenkov detector using 1,000 Tonnes of D2O viewed by almost 10,000 Photomultiplier tubes 20cm in diameter. The electronics chain is required to provide deadtimeless sub-nanosecond time and charge measurement for Photomultiplier pulses in the range of 1 - 1000 photo electrons. The electronics chain must handle background event rates in excess of 1 kHz and burst rates in excess of 1 MHz. The SNO electronics is implemented with three full custom integrated circuits and standard commercial ADCs, memory, and logic. The DAQ interface is VME compatible. We will describe the SNO electronic system design including novel features of the DAQ and trigger paths.
