Remember * * * these DAs are designed be unity gain and to handle approximately 1 volt p-p so be carefull of clipping if you drive much more than that level or alternatively, pad down the input to a 1 volt level.
Also, video DAs are designed to drive 75 ohms (the video world's standard distribution impedance), so you will get additional attenuation at the output if you are driving 50 ohms, and you may get current clipping. That said, some video DAs work quite well at 10 MHz/50 ohms/+13 dBm (= 1 V rms = 2.8 V p-p) if you modify the internal input and output impedances. In some cases, you can reduce the added phase noise by reducing the LF gain.
