3.1 100Base-TX Operation
3.2 10Base-T Operation
ICS1893CK-40, Rev. C, 06/02/09
During 100Base-TX data transmission, the ICS1893CK-40 accepts packets from a MAC and inserts
Start-of-Stream Delimiters (SSDs) and End-of-Stream Delimiters (ESDs) into the data stream. The
ICS1893CK-40 encapsulates each MAC frame, including the preamble, with an SSD and an ESD. As per
the ISO/IEC Standard, the ICS1893CK-40 replaces the first octet of each MAC preamble with an SSD and
appends an ESD to the end of each MAC frame.
When receiving data from the medium, the ICS1893CK-40 removes each SSD and replaces it with the
pre-defined preamble pattern before presenting the nibbles to its MAC Interface. When the ICS1893CK-40
encounters an ESD in the received data stream, signifying the end of the frame, it ends the presentation of
nibbles to its MAC Interface. Therefore, the local MAC receives an unaltered copy of the transmitted frame
sent by the remote MAC.
During periods when MAC frames are being neither transmitted nor received, the ICS1893CK-40 signals
and detects the IDLE condition on the Link Segment. In the 100Base-TX mode, the ICS1893CK-40
transmit channel sends a continuous stream of scrambled ones to signify the IDLE condition. Similarly, the
ICS1893CK-40 receive channel continually monitors its data stream and looks for a pattern of scrambled
ones. The results of this signaling and monitoring provide the ICS1893CK-40 with the means to establish
the integrity of the Link Segment between itself and its remote link partner and inform its Station
Management Entity (STA) of the link status.
For 100M data transmission, the ICS1893CK-40 MAC Interface is configured to provide a 100M Media
Independent Interface (MII).
During 10Base-T data transmission, the ICS1893CK-40 inserts only the IDL delimiter into the data stream.
The ICS1893CK-40 appends the IDL delimiter to the end of each MAC frame. However, since the
10Base-T preamble already has a Start-of-Frame delimiter (SFD), it is not required that the ICS1893CK-40
insert an SSD-like delimiter.
When receiving data from the medium (such as a twisted-pair cable), the ICS1893CK-40 uses the
preamble to synchronize its receive clock. When the ICS1893CK-40 receive clock establishes lock, it
presents the preamble nibbles to its MAC Interface. The 10M MAC Interface uses the standard MII
Interface.
In 10M operations, during periods when MAC frames are being neither transmitted nor received, the
ICS1893CK-40 signals and detects Normal Link Pulses. This action allows the integrity of the Link
Segment with the remote link partner to be established and then reported to the ICS1893CK-40’s STA.
