HD Radio connectivity
The HIT2 complies with HD Radio interface specifications as per Ibiquity's "RX_SSS_1108
HD Radio power efficient RF-IF and peripheral processing (power RIPP) specification", thus
providing an external HD Radio decoder with I/Q base-band signals and receiving the
decoded digital audio from it, as shown in Figure 5.
