AD9988 Evaluation Board spurs ever 62.MHz with ZCU102

I am using an AD9988 with zcu102 stock image based on the link below.

Using the iio scope default configuration on boot I'm seeing significant spurs at the LO frequency and every 62.5MHz.  The input is terminated and the DACs have been disabled. 

Is this behavior expected?
