Setting Up ParBERT 43G Clock Connections

64 Agilent 81250 ParBERT Installation Guide, February 2002

Figure 42 Setup Using More than 16 Data Modules

A setup like this can hold a total of up to 22 data generator/analyzer

modules.

To keep the high-speed cables as short as possible, the working height

for placing the DUT should be established between the bottom and the

middle frame.

Clock Connections

The MUX module requires a clock signal. It has to be synchronized with

the generator frontends.

The DEMUX module has a built-in clock data recovery (CDR) circuit that

allows to recover the clock from the incoming data. But the DEMUX

module can also be controlled by an external clock.
