I am using a AD9910 evaluation board, to generate a BPSK modulated signal. The carrier frequency will be 100Khz. I have set profile 0 with 100Khz, o degrees phase, and Profile 1 with 100Khz, 180 degrees phase. i'm switching the phase by using pins "PROFILE [0,1], at a rate of approximately 83uS. The problem is that when I use a scope i see discontinuities. this is shown by amplitude spikes where phase shifts occur.
I've tried changing the clock variables, but no luck.
