external AC-DC adapter, and an USB-B connector (USB) for connecting an external PC withinstalled Windows GUI control software.
Two input data signals supplied through the CML differential ports are sampled by an internal clockthat is derived form an input half-rate clock.
The input clock has a controlled phase shift capability that allows for selection of the optimal data
sampling point. The input half rate clock is divided by 2, and supplied to two outputs through;therefore, enabling a direct interface to an Error Detector. This feature simplifies measurements ofthe demultiplexed data. More details can be found in the AN_ASNT_DMUX64 document.
A Windows GUI (compatible with Windows XP, 7, 8 and 10) is used to control all adjustableparameters of the unit including demultiplexed data output amplitude, clock phase shift, commonmode voltage levels of the input clock signals, etc.
The Unit is powered by a single 9V supply delivered from an external AC-DC adapter connected tothe input socket on the back panel.
An example of the input eye for a 56Gbps PRBS7 signal is shown in Fig. 3.
