A reliable high-precision and high-performance streamer cable digitizer for marine seismic exploration is proposed. In this precise digitizer, there are total 16 data acquisition channels, each of which can be connected to hydrophones directly. Analog signals are digitized by 24-bit high precise Δ-Σ ADCs controlled by Field Programmable Gate Array (FPGA) in real time. Schemes of real time system control and remote synchronization are also well designed and realized in the digitizer based on the architecture of serial concurrent bus which is implemented by FPGA. The results indicate that this digitizer can meet the requirements of marine seismic exploration.
