SI
Stream Interface, Serial Interface, or Symbol Interface.
With reference to the MII/SI pin, the acronym ‘SI’ has multiple meanings.
• Generically, SI means 'Stream Interface', and is documented as such in this data
sheet.
• However, when the MAC/Repeater Interface is configured for:
– 10M operations, SI is an acronym for 'Serial Interface'.
– 100M operations, SI is an acronym for 'Symbol Interface'.
