Special Functions

SFD

Start-of-Frame Delimiter

Stream Interface

Serial Interface

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 the ICS

1890 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'.
