10/100 Base-T/TX Ethernet Ports
There are two 10/100 Base-T/TX Ethernet ports on KSZ8842-PMQL evaluation board and one
10/100 Base-T/TX Ethernet port on KSZ8841-PMQL evaluation board. The ports can be
connected to a traffic generator or analyzer via standard RJ45 connectors using CAT-5 cables.
Each port can be used as either an uplink to downlink. The ports support HP auto MDI/MDIX so
there is not need for cross over cables.
J1 = RJ45 connector for port 1
J2 = RJ45 connector for port 2
