External reference clock for Digital Discovery?
Hi,
we are evaluating to use a bunch of Digital Discovery boards for experimental physics; more specifically: to synchronise / control certain motors / detectors / other equipment.
(1) Is it possible to synchronise the Discovery to some external reference clock (10 MHz is quite common), in order to reduce temporal jitter?
(2) In another use case, we would like to control an experiment running at 5.204 MHz; it would be great if the system clock (100 MHz) could somehow be tweaked to
Hi @osti
1. The Sync mode on Digital Discovery uses re-sampling at 1.25ns (800MHz) resolution.
This uses the device triggering mechanism, so when using Sync mode the trigger options are not available.
2. At the moment only 100MHz base frequency is supported.
I'm planning to add option to be able to fine adjust this frequency, like:
50.00836820083682, 50.00985221674877, 50.01197604790419, ... 98.86567164179104, 98.87323943661971, 98.88, ... ,99.97714285714285, 100 MHz
