Can HMC856 works with positive supply?

HMC856 has two power supply, GND and VEE(-3.3V). Can I connect the GND pin to positive supply(+3.3V) and connect the VEE pin to ground? In my appilcation, the LVDS signal from the FPGA should be changed to the negetive CML level through a logic level translator and then input HMC586. Also, the signal passing through HMC586 is not DC balanced. It is weird to place SEVEN level translators around ONE HMC856 on the board.

I know that the CML interface consists 50 Ohms resistors pullup to the positive supply, and the signal voltage swings should be from VCC-0.6V to VCC. If I connect the power supply GND to +3.3V supply, will the logic level changes from −585mV~−20mV(when VR=GND) to 2.7V~3.3V(when VR=3.3V)?
