Spread Spectrum ASK™ is a combination of
traditional ASK combined with FSK dithering. This
modulation type goes under FCC part 15.247 digital
modulation allowing higher output power without
FHSS. The FSK dithering frequency, applied to the
ASK signal, is greater than the ASK data rate and
therefore, a traditional ASK/OOK receiver with
Figure 14. 33kbps, PA=6, ASK=7, ASKshape=2 (Fphd=2MHz, 209kHz internal loop filter).

500kHz noise bandwidth can be used. FSK is
applied using divider modulation Modulation[1:0]=2,
due to the high loop filter bandwidth requirement of
the ASK modulation. The ASK_PN_en signal
controls whether the dithering is a “010101”-pattern,
ASK_PN_en=0, or a “111101011001000”-pattern,
ASK_PN_en=1.
