Frequency of Clock Mixing Spurious Images in X4 and X4L Modes Figure 72 shows the location of spurious signals for X8 mode as a function of fSIG/fDAC. The addition of the fDAC/8 clock frequency for the first interpolation filter creates four new spurious signals. For a complex output, the nearest spurious signals are fDAC/8 offset from fSIG. For a real output, the optimum real output frequencies fSIG = fDAC × N/16 (N = 3 and 5), where the minimum spurious product offset from fSIG is fDAC/8. Figure 72. Frequency of Clock Mixing Spurious Images in X8 Mode The spurious signal amplitude is sensitive to factors such as temperature, voltage, and process. The following typical worst-case estimates to account for the variation over these factors are provided as design guidelines.
