Impedance matching for analog input of AD9288

Question asked by kulist on Oct 26, 2015

i have to link the diffierential sinewave output of an ASIC to the analog input of the AD9288.Since it is already a diffierentilal signal,I think maybe i dont need a transformer。So,if i link them with the  transmission line by AC coupling,and the differential  impedance

of the transmission line is 100 ohm。Should I use an 100 ohm Resistor make the shunt connection between the diffierential analog input of the AD9288 ?
