Pulse Width Distortion (PWD) 3ns (max) corresponds to 150Mbps high-speed communication

Toshiba's standard 4 channel digital isolators improve PWD within 3ns, perform clear eye patterns and offer a maximum data rate corresponding to 150 Mbps what is enabled by high carrier frequency and on-off keying control. These products simplify multi-channel designs such as isolated SPI communication by improving the channel matching within 3.5ns (Same Direction).
