ASK/FSK MODULATION with AD9106

Hello,

 

I need help on AD9106; in particular, can I generate a sine waveform (about 4MHz) modulated with a bitstream (telegram) ASK (255bit, 565kHz) or FSK (1023bit, 565kHz) and shaped with a gaussian profile of opportune duration? In case of FSK modulation, the RAM address counter (where are stored the FTW) can be managed by the DDS only (MSB output) or also by the base clock (a number of clocks for 1 address increasing, for example)? So I could dedicate a channel for gaussian profile and a channel for ASK/FSK modulated signal, making the multiplication between the two channels externally.

 

I hope someone can help me.

 

Thanks
