90 Mbps, 5000 Vrms — the isolation spec that matters for motor drives and medical
The ADUM2402CRWZ: With a 90 Mbps data rate and 32 ns max propagation delay, it handles high-speed SPI, UART, and general-purpose signal isolation without adding timing margin headaches. The 25 kV/µs common-mode transient immunity (CMTI) is the number to watch in motor-drive and inverter applications — fast-switching IGBT nodes can couple several kV/µs across the barrier, and this part's rating keeps the data path clean.
Channel count and direction — 2/2 split for isolated SPI or two bidirectional lines
The four channels are split 2/2 between Side 1 and Side 2, all unidirectional. That maps directly to isolated SPI (SCLK, MOSI from Side 1; MISO, SS from Side 2) or two independent isolated data paths. The 2.5 ns typical rise/fall time and 2 ns max pulse-width distortion mean the output waveform stays clean at 90 Mbps, so you don't need to derate for jitter on a long cable run.
