RJ45 100-megabit network port design plan

The common-mode filter inductor filters out common-mode interference on differential signals. The common-mode impedance selection range is 60Ω@100MHz to 120Ω@100MHz, with a typical value of 90Ω@100MHz. GDT discharge tube protection devices are used for circuit lightning protection, with a nominal voltage requirement of greater than or equal to 6V. The peak current requirement is greater than or equal to 50A. The peak power requirement is greater than or equal to 300 W. The equipment has a metal casing. Meanwhile, the single board can independently demarcate the interface ground. Therefore, the metal casing is directly electrically connected to the interface ground, and the ground of the single board is connected to the interface ground through a 1000pF capacitor.
