The KSZ8893FQL filters error frames, and thus does not implement the RX_ER output signal. To detect error frames
from RMII PHY devices, the SMTXER input signal of the KSZ8893FQL is connected to the RXER output signal of the
RMII PHY device.
Collision detection is implemented in accordance with the RMII Specification.
In RMII mode, tie MII signals, SMTXD[3:2] and SMTXER, to ground if they are not used.
The KSZ8893FQL RMII can interface with RMII PHY and RMII MAC devices. The latter allows two KSZ8893FQL
devices to be connected back-to-back. The following table shows the KSZ8893FQL RMII pin connections with an
external RMII PHY and an external RMII MAC, such as another KSZ8893FQL device.

Table 10. RMII Signal Connections
SNI (7-Wire) Operation
The serial network interface (SNI) or 7-wire is compatible with some controllers used for network layer protocol
processing. In SNI mode, the KSZ8893FQL acts like a PHY and the external controller functions as the MAC. The
KSZ8893FQL can interface directly with external controllers using the 7-wire interface. These signals are divided into
two groups, one for transmission and the other for reception. The signals involved are described in the following table.

Table 11. SNI Signals
The SNI interface is a bit wide data interface and therefore, runs at the network bit rate (not encoded). An additional
signal on the transmit side indicates when data is valid. Similarly, the receive side has an indicator that conveys when
the data is valid.
For half duplex operation, the SCOL signal is used to indicate that a collision has occurred during transmission.
