AO Sample Clock Timebase Signal

Version:
    Last Modified: August 30, 2018

    The AO Sample Clock Timebase signal is divided down to provide a source for AO Sample Clock. AO Sample Clock Timebase can be generated from external or internal sources, and is not available as an output from the controller.

    Delta-Sigma Modules

    The oversample clock is used as the AO Sample Clock Timebase. The cRIO controller supplies 10 MHz, 12.8 MHz, and 13.1072 MHz timebases. When delta-sigma modules with different oversample clock frequencies are used in an analog output task, the AO Sample Clock Timebase can use any of the available frequencies; by default, the fastest available is used. The update rate of all modules in the task is an integer divisor of the frequency of the AO Sample Clock Timebase.
