2  Hardware Description

2.1  Overview

The MCCD is a 8 output fast pulse driver with 60 ps rise time and a 8 output clock driver (TTL) with internal
reference clock or ext input.

2.2  Front Panel, Trigger Fan-out

The connectors at the front panel are for distributing one trigger signal from the TRG IN input to eight output 
SMA connectors. Instead of an external trigger signal the internal (10 MHz) or external clock signal can be 
fed to the output connectors by setting the internal jumper JP1, “Internal Trigger”, see Fig. 2.2.
