| The evaluation board provides the support circuitry required to operate the [[adi>AD9681|AD9681]] in its various modes and configurations. Figure 1 shows the typical bench characterization setup used to evaluate AC performance. It is critical that the signal sources used for the analog input and clock have very low phase noise (ideally ~100 fs rms jitter) to realize the optimum performance of the signal chain. Proper filtering of the analog input signal to remove harmonics and lower the integrated or broadband noise at the input is necessary to achieve the specified noise performance.\\ | The evaluation board provides the support circuitry required to operate the [[adi>AD9681|AD9681]] in its various modes and configurations.
