Integrated Approach to SPI using Digital Isolator Technology

SPI is the bus used for isolated IC to IC communications. Use of unidirectional lines makes it easy to isolate. But since there no support for interrupts, and in band addressing for target devices, extra isolated channels usually surround it. The clocking scheme also links the bus speed to the propagation delay of the isolation. In this webinar we will look at new integrated SPI digital isolator solutions that address these shortcomings.
