SNI Interface (7-wire) Operation
The SNI (Serial Network Interface) is intended to interface with some controllers used for network layer protocol processing.
KS8993 acts like a PHY device to external controllers. This interface can be directly connected to these type of devices. The
signals are divided into two groups, one being for transmission and the other being the receive side. The signals involved are
described in the table below.
This 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. Likewise, the receive side has an indicator that conveys when the data is valid.
For half-duplex operation there is a signal that indicates a collision has occurred during transmission.
