     I want use the external voltage reference of AD9484,but the datasheet is confusing ,as it shows,



BIT 7,6 should be 0 1,use  import Vref, voltage range is 0.59V to 0.8V, but bit 4 to 0 show that Input voltage range is 1.18 to 1.6V, is there any relationship between them? and how should I set the

external voltage?

     thanks a lot !!!
