I'm not quite familiar with ADI product families and I'm a little bit confused after reading the datasheets of AD9172 and AD9173. It seems that their descriptions are nearly the same, and the prices for their evaluation board are the same, even though their own prices differ greatly. I'm wondering what makes them different, and how would I choose between them? Thanks a lot.
The AD9171 is rated for up to 6Gsps sampling rate and supports up to 500Msps at the DAC input while the AD9172 is rated for 12Gsps and supports up to 1500Msps at the data input.
