We are updating an IQ Modulator design that currently uses an AD9777 DAC to drive the I and Q inputs of an ADL5390 as per the ADL5390 data sheet (figure 32).
The AD9777 DAC is now listed as 'Not Recommended for New Designs'
What DAC should we use in the revised design.
How about the AD9125? http://www.analog.com/en/products/digital-to-analog-converters/da-converters/ad9125.html
This is what is recommended as an alternative part of the the AD9777 webpage.
