Ethernet Interface
The Falcon features an on-board Micrel KSZ9021/31RNI PHY and EG20T embedded Ethernet
controller. The controller provides a standard IEEE 802.3 Ethernet interface for 1000Base-T,
100Base-TX, and 10Base-T applications. An RJ-45 connector is located at location J6. Drivers
are readily available to support a variety of operating systems.

One rugged, 8-pin, right-angle, latching Ethernet connector (J6) is provided to make connection
with a Category 5 or 6 Ethernet cable. The Ethernet controller auto-negotiates connection speed.
The interface uses IEC 61000-4-2-rated TVS components to help protect against ESD damage.
