Integrated isolated RS422/RS485 transceiver with on-board DC/DC
It delivers a 20 Mbps data rate over a single unidirectional channel pair (one driver, one receiver), with 2500 Vrms of galvanic isolation between the logic-side and line-side interfaces.
30 kV/µs CMTI — what it means for noisy environments
The common-mode transient immunity is rated at 30 kV/µs minimum. In practice this means the receiver output stays valid when large voltage spikes slam across the isolation barrier — the kind of event you get from a motor drive IGBT switching, a relay bank, or a nearby lightning strike on a long cable run. A part with lower CMTI (some peers spec 25 kV/µs) may glitch or lose data under the same transient. For factory-floor RS485 networks, this margin buys reliability without external transient suppression on the logic side.
The 32-BGA (15x11.25 mm) module uses a BGA footprint with 1.27 mm ball pitch — standard for a 4-layer PCB with a ground plane under the module. The package carries the isolated power transformer internally, so the board layout only needs to route the supply and data lines to the BGA pads.
