hi ron,
you must connect the sample clock generator
to both adc boards in a dual adc system.
to do this, you'll need a 2:1 power splitter
(about $25 from minicircuits).
you can purchase sample clock generators
from valon technologies.
the ADC2x1000-8 and ADC1x3000-8
yellow blocks will sync

I know this happened on the iBobs, but I'm not sure it is still the case on the
ROACH (or ROACH2).
Ron, are
No. I want to have both ADC boards be of the
same type. The new concern I have is that you
express doubt that the yellow blocks will
sync the two ADC's on our ROACH board. If one
ADC is out of sync with the other, I expect
the ADC generating the FPGA clock will be in
sync but the other ADC may be
3 matches
