6.3 Functional Block: 100Base-X PCS and PMA Sublayers
6.3.1 PCS Sublayer
6.3.2 PMA Sublayer
ICS1893Y-10 Rev F 1/20/04
The ICS1893Y-10 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.
The ICS1893Y-10 100Base-X PCS sublayer provides two interfaces: one to a MAC/repeater and the other
to the ICS1893Y-10 PMA sublayer. An ICS1893Y-10’s PCS sublayer performs the transmit, receive, and
control functions and consists of the following:
•
•
•
Note:
The ICS1893Y-10 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:
•
•
•
•
•
PCS Transmit sublayer, which provides the following:
PCS Receive sublayer, which provides the following:
PCS control functions, which provide:
Link Monitoring
Carrier Detection
NRZI encoding/decoding
Transmit Clock Synthesis
Receive Clock Recovery
– Parallel-to-serial conversion
– 4B/5B encoding
– Collision detection
– Serial-to-parallel conversion
– 4B/5B encoding
– Carrier detection
– Code group framing
– Assertion of the CRS (carrier sense) signal
– Assertion of the COL (collision detection) signal
ICS1893Y-10 Data Sheet - Release
When configured for 100M Symbol mode operations, the MAC/Repeater Interface bypasses most
of the PCS. When the ICS1893Y-10 MAC/Repeater Interface is in this mode, most of its PCS
Transmit and Receive modules are inactive. However, its PCS control functions (CRS and COL)
remain operational.
