In the AFE58xx data sheets the Vin for hi is specified from 2V to 3.3V. Is this correct, since DVDD is 1.8V. Can the SPI port on the AFE58xx be driven by 1.8V IO from a FPGA?

Yes, though I am pointing the question a little more. In the reference, there is a PWM signal or external to drive a waveform. Assume we use an external signal from some source and then we do this for...
