SYNCOUT

Category: Hardware
Product Number: AD5932

Hello,  I have two AD5932's,  one on the evaluation board and one on a breadboard.  For neither of them can I get SYNCOUT to work, in either mode, just a flatline.  That is using the SW with the eval board and my own code via a Raspberry Pi,  I am at a complete loss.  I have checked the SPI data via a scope (and a sniffer) and it works fine.  The sweeps are correct, I can turn on/off the MSB, get a sine or triangle wave but no SYNCOUT.   My register values are what you would work out and also match the evaluation SW.   Any Ideas?  

One other strange thing   is that my one board give me a sweep, but the output (the sweep) ends at the end of the sweep, instead on continuing with the last frequency?
