Introduction
The
ICS1889
is a nibble to bit stream and bit stream to nibble
processor. When transmitting, it takes sequential nibbles
presented at the Media Independent Interface (MII) and
translates them to a serial bit stream for transmission on the
media. When receiving, it takes the serial bit stream from the
media and translates it to sequential nibbles for presentation
to the MII. It has no knowledge of the underlying structure of
the MAC frame it is conveying.
When transmitting, the
ICS1889
encapsulates the MAC
frame (including the preamble) with the start-of-stream
(SSD) and end-of-stream (ESD) delimiters. When receiving,
it strips off the SSD and substitutes the normal preamble
pattern and then presents this and subsequent preamble
nibbles to the MII. When it encounters the ESD it ends the
presentation of nibbles to the MII. Thus, the MAC
reconciliation layer sees an exact copy of the transmitted
frame.
During periods when no frames are being transmitted or
received, there is a requirement to signal and detect the idle
condition. This allows the higher levels to determine the
integrity of the connection between the node and the hub. A
continuous stream of ones is transmitted to signify the idle
condition, the receive channel includes logic that monitors
the IDLE data stream to look for this pattern and thereby
establish the link integrity.
