The sinusoids being produced by both channels looks like they aren't being sampled fast enough digitally.
Is there a way to speed up the sampling or have I done something wrong with the inputs?
Reference Clock is a 100 MHz, sinusoidal at 1.8 Volts (no offset)
Both outputs are set at 5 Mhz, and tested at a lower frequency of 2 Mhz and 4 MHz, but same problem.
This is the first time I'm actually dealing with a DDS system.
