... CMOS driver (default): connect an oscilloscope/ spectrum analyzer to CMOS_OUT (J7). Note that R106 must be installed to connect J7 to the CMOS out on the AD9912. Connect DUT FILTER OUT (J5) to FDBK IN (J6). Note that this step is not necessary if R20 (near J5) and R18 (near FDBK IN/J6) are stuffed. Rev Page AD9912/PCBZ ...

... AD9912/PCBZ DIFFERENTIAL FILTER DESIGN The differential filter advantages include fewer components and a simpler design when the AD9912 is used in an actual design. Note that the 100 Ω differential source impedance is internal to the IOUT/IOUB driver. Also, note that the ac coupling between the IOUT differential pair and the FDBK_IN differential pair is critical ...
