I am having problems finding an Analog Device's DAC that can suit my needs.
I would really appreciate any help you can give.
If we can find a DAC that suits my needs they I will recommend it to all of my customers.
Thanks and Regards,
What kind of performance do you need from the DAC? For high performance applications, you would not typically use the FPGA as the clock source for the DAC since there are better performance clock sources available, such as ADI's ADF series of PLLs.
I'm trying to understand your question better. When you say max data rate of 600 MSPS, I think you mean max DACCLK rate. Is that true? Will you always be transferring data to the DAC (what we would call the "data rate") at 74.25 MSPS? And then you want to interpolate it to as high as 594 MSPS DAC Update Rate?
For these functions and DAC rate, I would suggest you check the AD9122 (16-bit, 1.2 GSPS dual) or the AD9785 (12-bit, 800 MSPS dual).
