AD9914 and FPGA

Question asked by sebastien on Sep 12, 2012

Hi everyone,

 

I want to use the AD9914 to generate pseudo-arbitrary RF pulses in RZ format (eg one sequence is : pulse1 at 1.3 GHz with 20 ns duration, then no signal during 60 ns, then frequency2 at 1.31 GHz with 20 ns duration etc... one sequency is constitutive of 100s of frequencies). There are thousands of sequences like this with different frequences in it, and the time between each sequence should be about 1ms.

 

I think that I need a FPGA to drive my AD9914 on the parallel port. Is there some experience here that is comparable ? I would need some advices,

 

Thank you in advance
