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

Hi Yi, How are you? Sorry there was a typo. the following is the correct number: for your question #1, the AFE5809 differential inputs have very high impedance (around 10Kohm differentially). Please look at the data sheet page 46. figure 79. (b) ADC Input Clocks. Thank you again! Best regards, Chen
