AD9957 BFI Mode Questions

Hi there,

A couple of questions on the AD9957 Data Sheet Rev C.

1.       In Table 12 , it seems to suggest that there is no “Input Scale Multiplier” in the BFI mode.

Does that mean that ramping is not supported in the BFI mode?

2.       Figure 27 shows 4x half-band filters.  But the description on page 23 states that there are two additional half band filters for a 16x interpolation in the BFI mode.

Can anyone please help to clarify?
