The graph supplied on this slide shows the common mode transient immunity provided by the Isolator µModule Technology, demonstrating the impressive isolation performance. The plot in red, shows several common mode transients introduced to the system before, during and after communication. The slew rate of the transients are roughly 1kV per 28ns or 35kV/µs. The driver, in blue, continues to drive data to the receiver, in green, in a loop back configuration and consistently outputs the data on RO with no jitter or corruption of data. The propagation delay is from two transmissions across the barrier with the loopback through the RS485 driver and receiver back to the logic side RO output. While other isolation solutions may only hold state during a transient event, the Isolated µModule Technology provides continuous communication during these harsh system events, with guaranteed high common mode transient immunity of 30kV/µs.
