Magnetics Information
The LXT901 and LXT907 require a 1:1 ratio for the receive transformer and a 1:
transmit transformer on the twisted-pair interface. The AUI Interface requires a 1:1 ratio for both
the transmit and receive transformers. Designers should test and validate magnetics for system
requirements before committing to a specific component.
