EVAL-ADL5569: About how to use as Differential input and Single-end output

Question

Hi, 
 Our customer is considering to use ADL5569. 
 About EVAL-ADL5569, he wants to use it that the condition is differential input and single-end output. 
 How does he change resisto value for use above condition? 
 I think the input stage is already for differential input but the output stage is not for single-end output. 
 I am understanding should change resistor of output stage for use single-end output. 
 Please tell me how to use EVAL-ADL5569 as the differential input and single-end output. 
 I am very happy if I can know concrete value of resistor. 
 Best Regards, 
 Tomohiro

Hi Kakehi-San, 
 Normally the two output pins are ac-coupled and connected to a 100 ohm resistor (see Figure 38 in the datasheet). If you only want a single ended output, then you would connect a 50 ohm resistor between the unused output and ground. So the output paths would look like this. 
 VOP - AC Coupling Capacitor - Load (50 ohms) 
 VON - AC Coupling Capacitor - 50 ohm resistor to ground. 
 If you do this, the voltage gain will be 6 dB lower.
