This section provides a brief description of the alternative 
analog input drive configuration using the 

 . When 

using this particular drive option, some components need to be 
populated as listed in Table 16. For more details on the 

differential driver, including how it works and its optional pin 
settings, consult the 

 data sheet. 

To configure the analog input to drive the 

 instead of 

the default transformer option, the following components need 
to be added, removed and/or changed: 

•  Remove C1 and C2 in the default analog input path. 

•  Populate R3 and R4 with 200 Ω resistors in the analog 

input path. 

•  Populate the optional amplifier input path with all 

components, except R594, R595, and C502. Note that to 
terminate the input path, only one of these components, 
(R9, R592, or R590 and R591) should be populated.  

•  Populate C529 with a 5 pF capacitor in the analog  

input path. 

Currently, R561 and R562 are populated with 0 Ω resistors to 
allow signal connection. This area allows the user to design a 
filter if additional requirements are necessary.
