Abstract :
A data acquisition module based on monolithic high-speed flash-ADC (analog-to-digital converter) chips (8-b resolution) is described. Four fully independent channels, with 250-MHz sampling rate and a 2-Kbyte buffer memory each, can be combined (interleaved) in one channel to achieve an effective 1-GHz sampling rate with a total of 8-Kbyte memory depth. The double Eurocard board supports standard 16-b VMEbus protocol for high-speed readout. The board is essentially self-contained and can be used cost-effectively in small applications as well as in large experimental setups.<>
