INTERPOLATION FILTER ARCHITECTURE
The AD9776/AD9778/AD9779 can provide up to 8× interpola-
tion, or the interpolation filters can be entirely disabled. It is
important to note that the input signal should be backed off by
approximately 0.01 dB from full scale to avoid overflowing the
interpolation filters. The coefficients of the low-pass filters and
the inverse sinc filter are given in Table 13, Table 14, Table 15,
and Table 16. Spectral plots for the filter responses are shown in
Table 13. Half-Band Filter 1
