Hi, The company I work for is currently looking to redesign a board that currently uses the AD9957. This chips runs at 1GSPS and from what I have seen is currently the fastest DDS Analog Devices is selling. I was curious as to whether anyone knew if a faster chip is currently in design or anything. I did not see any news on the actual website. I was also not able to find anything out when I called, and they suggest that I post here. If anyone could provide any information on this or give me a heads up to any links if i just missed some announcement etc. I would greatly appreciate it.
I would recommend looking at ADI's TxDACs offerings, like the AD9122. The AD9957 probably has
more interpolation but the AD9122 sample clock is higher.
