Loopback Support
The KSZ8862M provides loopback support for remote diagnostic of failure. In loopback mode, the speed at both PHY
ports will be set to 100BASE-TX full-duplex mode. Two types of loopback are supported: Far-end Loopback and Near-end
(Remote) Loopback.
Far-end Loopback
Far-end loopback is conducted between the KSZ8862M’s two PHY ports. The loopback path starts at the “Originating.”
PHY port’s receive inputs (RXP/RXM), wraps around at the “loopback” PHY port’s PMD/PMA, and ends at the
“Originating” PHY port’s transmit outputs (TXP/TXM).
Bit [8] of registers P1CR4 and P2CR4 is used to enable far-end loopback for ports 1 and 2, respectively. Alternatively, Bit
[14] of registers P1MBCR and P2MBCR can also be used to enable far-end loopback. The port 2 far-end loopback path is
illustrated in the Figure 12.
Near-end (Remote) Loopback
Near-end (Remote) loopback is conducted at either PHY port 1 or PHY port 2 of the KSZ8862M. The loopback path starts
at the PHY port receiving 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 P1PHYCTRL and P2PHYCTRL is used to enable near-end loopback for ports 1 and 2, respectively.
Alternatively, Bit [9] of registers P1SCSLMD and P2SCSLMD can also be used to enable near-end loopback. The both
ports 1 and 2 near-end loopback paths are illustrated in the following Figure 13.
