ADL5511 envelope interface to AD9288

I'm trying to figure out the smallest way to interface the ADL5511 envelope detect output to the AD9288.  I don't need the full bandwidth of the detector but up to 50 MHz.  I do need the output of the ADL5511 to be DC coupled to the AD9288 though.  I'm trying to see if there is an implementation smaller than a difference amplifier + single ended to differential converter.  Or maybe what kind of degradation comes with using the AD9288 single ended up to say 50 MHz input?

The other concern is the differential input voltage of the AD9288 is only 1 Vpp so I need to scale down the voltage to fit within the range of the ADC.
