ADA4938 Output Termination for Driving SMA Cable

Hello,

I am trying to use ADA4938 as a differential driver for transferring signal from board to board (DC coupling through SMA cable). I am wondering what is the output impedance of ADA4938 when it's configured as a DC coupled differential driver? And how should I terminate the output of ADA4938 to drive signal through a SMA cable (50 ohm)?

 

The following figure is one example I found from the ADA4938 data sheet. Are the two 50 ohm resistors at the output used for matching the output impedance with 50 ohm cable?


Thanks.
