REMOTE PHY LOOPBACK

This loopback mode checks the line (differential pairs, transformer, RJ-45 connector, Ethernet cable) transmit and

receive data paths between the KSZ9567R and its Ethernet PHY link partner, and is supported for 10/100/1000 Mbps

at full-duplex.

The loopback data path is shown in Figure 4-2 and functions as follows:

• The Ethernet PHY link partner transmits data to the KSZ9567R PHY port.

• Data received at the external pins of the PHY port is looped back without passing through the MAC and internal

switch fabric.

• The same KSZ9567R PHY port transmits data back to the Ethernet PHY link partner.
