The ADuM4154 has four high-speed channels. The first three channels, CLK, MI/SO, and MO/SI (the slash indicates the connection of the particular input and output channel across the isolator) are optimized for either low propagation delay in the B grade, or high noise immunity in the A grade.
SPI (Serial Peripheral Interface) communication is one of the most popular protocols for sending data between microcontrollers and different peripherals.
It is a synchronous protocol; the clock signal is provided by the master.
