Bonjour,
J'ai pas bien compris la phrase en gras, (à la page 11 du document ci-joint)
Four 49.9Ω, 1% resistors are required for proper termination of the TX and RX transmission lines. If the board layout necessitates long traces between the ENCX24J600 and Ethernet transformers, the termination resistors should be placed next to the silicon instead of the transformers.
