KSZ8863MLL/FLL/RLL
Near-end (Remote) Loopback
Near-end (Remote) loopback is conducted at either PHY port 1 or PHY port 2.of the KSZ8863MLL/FLL/RLL. The
loopback path starts at the PHY port’s receive inputs (RXPx/RXMx), wraps around at the same PHY port’s PMD/PMA,
and ends at the PHY port’s transmit outputs (TXPx/TXMx).
Bit [1] of registers 26 and 42 is used to enable near-end loopback for ports 1 and 2, respectively. Alternatively, the MII
Management register 31, bit [1] can be used to enable near-end loopback.
The near-end loopback paths are illustrated in the following figure.
