1 Introduction
The xTDC4 is a common-start time-to-digital converter. The timestamps of leading or trailing
edges of digital pulses are recorded. The xTDC4 produces a stream of output packets, each
containing data from a single start event, i.e. the relative timestamps of all stop pulses that
occur within the user defined range.
