Two 9-channel comparators interpret the incoming data and clock signals as either high or low, depending on where the user-programmable threshold is set. The threshold voltage of each pod is individually programmed, and the voltage selected applies to the clock channel as well as the data channels of each pod A field programmable gate array FPGA bridges the 1394 interface to the rest of the acquisition board components.
