physical-layer device

The ICS1893BF is a physical-layer device, also referred to as a ‘PHY’ or ‘PHYceiver’.

(The ICS1890 is also a physical-layer device.)

SFD

Start-of-Frame Delimiter

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 Interface is configured for:

– 10M operations, SI is an acronym for 'Serial Interface'.

– 100M operations, SI is an acronym for 'Symbol Interface'.
