Forum Post: RE: AFE5809: Question on Differential termination resistor location for ADC clocks input

Hi Chen, Last night we checked with mature product's SCH design( AC caps--->100ohm --> AFE, not follow with 5809 datasheet) , and we did hands-on experiments, it turned out that placement of resistor does not matter , we tested resistor before or after the AC caps. Both worked fine. Thanks for disscusing.
