6.2.5 Auto-Negotiation: Progress Monitor
Under typical circumstances, the Auto-Negotiation sublayer can establish a connection with the
ICS1893BF’s remote link partner. However, some situations can prevent the auto-negotiation process from
properly achieving this goal. For these situations, the ICS1893BF has an Auto-Negotiation Progress
Monitor to provide detailed status information to its Station Management (STA) entity. With this status
information, the STA can diagnose the failure mechanism and – in some situations – establish the link by
correcting the problem.
When enabled, the auto-negotiation process typically requires less than 500 ms to execute, independent of
the link partner's ability to perform the auto-negotiation process. Typically, an STA polls both the
Auto-Negotiation Complete bit (bit 1.5) and the Link Status bit (bit 1.2) to determine when a link is
successfully established, either through auto-negotiation or parallel detection. The STA can then poll the
Auto-Negotiation Link Partner Ability Register and determine the highest-performance operating mode in
common with the capabilities it is advertising.
6.3 Functional Block: 100Base-X PCS and PMA Sublayers
The ICS1893BF is fully compliant with clause 24 of the ISO/IEC specification, which defines the 100Base-X
Physical Coding sublayer (PCS) and Physical Medium Attachment (PMA) sublayers.
6.3.1 PCS Sublayer
The ICS1893BF 100Base-X PCS sublayer provides two interfaces: one to a MAC and the other to the
ICS1893BF PMA sublayer. An ICS1893’s PCS sublayer performs the transmit, receive, and control
functions and consists of the following:
PCS Transmit sublayer, which provides the following:
– Parallel-to-serial conversion
– 4B/5B encoding
– Collision detection
PCS Receive sublayer, which provides the following:
– Serial-to-parallel conversion
– 4B/5B encoding
– Carrier detection
– Code group framing
PCS control functions, which provide:
– Assertion of the CRS (carrier sense) signal
– Assertion of the COL (collision detection) signal
6.3.2 PMA Sublayer
The ICS1893BF 100Base-X PMA Sublayer consists of two interfaces: one to the Physical Coding sublayer
and the other to the Physical Medium Dependent sublayer. Functionally, the PMA sublayer is responsible
for the following:
Link Monitoring
Carrier Detection
NRZI encoding/decoding
Transmit Clock Synthesis
Receive Clock Recovery
