Application Circuit

H7001NL , H7500NL , H7800NL

The above circuit is a simple interface for a gigabit transformer connection between the silicon and connector. It is highly recommended

that the cable side center taps of each transformer be terminated to 75

Ω resistors and that the four center taps be terminated to an EFI

capacitor prior to ground termination.
