I would like to use the AD9959 to produce freuqencies from 1Hz to 25MHz. In order to go down to 1Hz frequency, a transformer can't be used on the DAC outputs. How would one use the AD9959 DAC ouputs without a transformer? Would one termnaite both to AVDD though 50 ohms, but only use oneof them going onto the AAF? Could a resistive combiner be used to use both outputs?
