10/100 Ethernet

Considerations:
● 10/100 relates to the data rate in Mbps (i.e. 10Mbps and 100Mbps)
   → For 10 Base-T, data is transmitted over 2 UTP (unshielded twisted pairs) using a 10MHz clock
   → For 100Base-TX, data is transmitted over 2 UTP using a 125MHz clock
● For these data rates the parasitic capacitance needs to be taken into account to preserve signal integrity
● The 4 data lines below (Tx+/- and Rx+/-) are being protected against intra-building (i.e. 100A, tP=8/20us) lightning transients by a two stage protection scheme
