IXF1110 MAC Unused Ports
Cortina recommends the following be used to disable an unused port. The SPI4-2 TSTAT
status bus will always reflect status for ten ports regardless of the number of IXF1110 MAC
unused ports. Any port which is disabled will have a constant status of SATISFIED. RSTAT
must also be input to reflect the status of all ten ports regardless of how many are disabled.
Optical Module Connections to the IXF1110 MAC
SFP-to-IXF1110 MAC Connection
The IXF1110 MAC SerDes and Optical Module interfaces allow system designers to
connect the IXF1110 MAC to various optical transceivers. When using Small Form Factor
Pluggable (SFP) optical transceivers to connect to the IXF1110 MAC, all SerDes and
Optical Module status pins are used. Use

3. TX SerDes pairs can be left unconnected.
4. RX SerDes pairs should be connected to ground.
