Note:
Application Information
Magnetics Information
The LXT971A Transceiver requires a 1:1 ratio for both the receive and transmit transformers. The
transformer isolation voltage should be rated at 2 kV to protect the circuitry from static voltages
across the connectors and cables. For transformer/magnetics requirements, see
Before committing to a specific component, contact the manufacturer for current product
specifications and validate the magnetics for the specific application.
