Ad9361 Sampling Rate Issues

We have used the drivers for AD9361 developed for Linux OS.


And we have converted the same driver code for VC++. We are able to configure and get the desired the signals but the accuracy of configuration is not Guaranteed.  For example, the Sampling Frequencies are not getting configured in normal way. We desired a sampling frequency of 500KHz and the driver doesn't seem to encourage this configuration. We tried the TRX clock paths as


{768000000,  24000000,   8000000,  4000000,  2000000,  500000}.


Please let us know if we have missed something. Also, whatever the sampling frequency we desire and request for the same the driver returns a sampling frequency configured with an nearly 10% offset.


Thanks in advance.
