100 MBS, 8 Bit Data Acquisition and Zero Suppression System for the DO Detector

The DO central tracking system produces a wide range of waveforms that must be digitized at a rate greater than 80 MHz. The 8,224 channels in this system create over two megabytes of data for every p-p crossing. Such a data rate can be tolerated if the null data is removed before it reaches the first data bus. We describe the tracking systems's 8 bit, 100 megasample per second digitizer and a channel-level, data reduction device implemented in a semi-custom integrated circuit.
