Dac help needed to generate sine waveform from Altera FPGA

Hi, My application needs to generate a sine wave of 10 to 20 samples per period. I am using Altera Cyclone 3 FPGA. Can anyone suggest which DAC I should be using. Also inputs as to how to go ab...

You need to do a little more research on your own first. You have missed several critical requirements, i.e., what is your highest frequency output (that you happen to want 10 or 20 samples at) and what is the dynamic range you require (this determines the number of bits in the DAC).

You could also work backwards; look at the ADC/DAC boards that Terasic has, and see if they are sufficient.
