Pulsing Vcc for ADL5321

I would like to power up and power down the ADL5321 quickly in order to save power in my system. I only need the device to be operational for 10-20ns at a time, then powered down for many microseconds. The faster the switching time, the more power I can save in the long run. I plan on using a pFET connected to 3.3V to act as a switch, with the bias capacitors between the pFET and 3.3V.

 

Is there anything limiting the ADL5321 from achieving this? Are there better ways to go about this?
