ADuM1401 with 90Mbps input signal

Hello,

I want to use ADuM1401 to isolate MCU and ADC.

The supply current of ADuM1401 is 31mA per channel when the frequency is 90Mbps, does it means the input signal current should be 31mA? As SPI driving current is several mA, how can I connect these two part together under high speed communication.
