Figure 66. HB2, Odd Filter Modes
As shown in Figure 65 and Figure 66, the center frequency in
each mode is offset by ¼ of the input data rate (fIN2) of the filter.
Mode 0 through Mode 3 do not modulate the input signal. Mode 4
through Mode 7 modulate the input signal by fIN2. When operating
in Mode 0 and Mode 4, the I and Q paths operate independently,
and no mixing of the data between channels occurs. When
operating in the other six modes, mixing of the data between
the I and Q paths occurs; therefore, the data input to the filter
is assumed complex. Table 20 summarizes the HB2 modes.

Figure 67 shows the pass-band filter response for HB2. In most
applications, the usable bandwidth of the filter is limited by the
image suppression provided by the stop-band rejection and not
by the pass-band flatness. Table 21 shows the pass-band flatness
and stop-band rejection the HB2 filter supports at different
bandwidths.

Half-Band Filter 3 (HB3)
HB3 has eight modes of operation that function the same as HB2.
The primary difference between HB2 and HB3 are the filter
bandwidths. Table 22 summarizes the filter modes for HB3.
