Will SPI be stable when the signals are like these?

Hi everyone

 

I am using AD5760.

Here come two diagrams of the SPI signals.

1. As can be seen from the first diagram, there are many large "ringings" . I think these ringings will decrease the performance of the DAC.

What could be done to remove or reduce the amplitude of the ringings?

2. The DAC is controlled through a microcontroller. And the clock diagram is shown below:

The DAC can work actually. My question is will DAC be unstable if a clock signal like this is given?

 

 

Thank you very much.
