Amplifying digital signal by ADA4870

Hi supporter,

I'm going to drive a series connected high power LED (http://www.ledengin.com/files/products/LZ4/LZ4-00DB00.pdf ) with a 30 to  50 MHz modulation frequency (square or sinusoidal wave)

aim to the output current capability and the voltage swing, i chose ADA4870 as my amplifier.

 

My issue is, the voltage source is a square wave that output from FPGA (LVTTL). If i want to amplify this digital signal by ADA4870, what should i notice on my design? or just set the configuration as the analog amplifier?

 

Any help would be appreciated.
