Overview

The CAEN Mod. DT4700 clock generator is a compact and easy to use desktop module that allows an easy synchronization of CAEN VME, NIM and desktop digitizers. It features 10 differential LVDS outputs, compatible with A317 clock distribution cable, each providing 50 or 62.5 MHz clock signal (switch selectable) required for the synchronization procedure. It also allows the possibility of working as a fan-out of a clock coming from another external source with a maximum frequency of 300 MHz. The DT4700 can also be powered through the USB port on the rear panel or, using the included power split cable, from your digitizer supply. In addition the DT4700 can also be operated as a general purpose Fan-Out.
