5.6 Ethernet
The Ethernet interface uses an RMII Ethernet Physical Layer Transceiver (PHY) (U11), connected to an
RJ45 standard Ethernet connector (J18) with integrated magnetics and status indicators. The Ethernet clock
is sourced from a precision 50 MHz crystal oscillator (OSC1) connected directly to the Ethernet PHY.
