IGEP COM AQUILA uses LAN8720 Transceiver transceiver to add Ethernet communication. [{{#lst:Template:Links|IGEP_AQUILA_EXPANSION_ISEE_Schematic}} IGEP AQUILA EXPANSION Public Schematics ] adapts SODIMM lines for a RJ-45 connector.

* For Ethernet data lines: TX differential lines (ETN_TXN (19) and ETN_TXP(21)) and RX differential lines (ETN_RXN (23) and ETN_RXP(25))**Equal length and symmetric with regards of shape, length, and via count.**Maintain symmetry and isolate 100 ohm differential impedance in the layout traces.**Isolate differential pairs from nearby signals and circuitry to mantain maintain the signal integrity.*Among PHY vendors, the 25mm rule is considered good design practice for EMI considerations. The intention is to isolate the PHY from the magnetics.*Common mode capacitors in data lines are not necessary because IGEP COM AQUILA includes them.*If the magnetic is a discrete component: **The distance between the magnetic and the RJ-45 needs to have the highest consideration and be kept to under 25mm of separation.**The distance between the SODIMM and the magnetics needs to be 20mm or greater.
