C.1.10.3 External Cables

The MII port supports an 18 inch (0.5-meter) long, 40-conductor, 20 signal-ground, STP cable. The single-ended impedance of the cable is 68 ohms (+/-10%). The propagation delay for each twisted-pair, measured from the MII connector to the PHY, does not exceed 2.5 nanoseconds.

The RJ45 Ethernet port supports a Category 5, UTP cable for the 100BASE-TX, and a Category 3, 4, or 5 UTP cable for the 10BASE-T operation.

The maximum cable segment lengths for the 100BASE-TX and 10BASE-TX are 300 feet (100 meters) and 3000 feet (1000 meters), respectively.
