1-1 Clock Domains Summary
The clock domain concept was already explained in “What is a
Clock Domain” on page 199. Here is a short summary:
A SOC Series test system supports two different clock domains.
• The digital clock domain
• The analog clock domain
Digital and Analog Clock Domain
An analog module can either be connected to the digital clock
domain or to the analog clock domain. This means that the master
clock signal supplied to the module is that of the active clock
source for the domain the module is connected to.
The selection of the clock domain to which the analog module
shall connect to is done in the Clock Domain Setup page of the
Analog Setup Tool, as shown above.

* The WGC has its own on-board clock generation, independent of the
domain clocks.
The TIA needs no clock signal from the system
