Up to 9216 fast discriminators are required for processing signals of the Fermilab silicon strip detector preamplifiers in experiment E789. signals exceeding a preset discriminator threshold voltage are first stored in a clocked latch and then delayed by three 19 ns clock cycles with a shift register. Discriminators are organized in 75 identical 128-channel subsystems. Each has four 32-channel P.C. boards housed n a signal routing motherboard. Eight 16-channel line driver boards transfer events from the motherboard through cables to the remote processing electronics. Three subsystems fit into the frame of a standard CAMAC crate. This paper describes the design considerations of the system and its performance, based on several months of testing the completed system.
