    The smaller EVM version shows the customer the space required for their design. This circuit provides an isolated, 20 Mbps, 3.3V to 5V RS-485 interface using the ISO3086T isolated RS-485 transceiver and the TPS76350 high accuracy linear regulator. This circuit achieves signal and power isolation and at the same time decrease board space and power consumption.
