Is it possible to output prestored sinewaves with the frequency tuning words coming from the RAM and the clock for the RAM address coming from DDSx MSB?
Yes it is. Here is an example RAM vector and regval file. The files generate a chirp waveform from a list of DDS tuning words stored in SRAM. The DDS MSB is the SRAM address counter clock.
