7.5.11
10Base-T Operation: Twisted-Pair Transmitter
The 10Base-T Twisted-Pair Transmitter is functionally similar to the 100Base-TX Twisted-Pair Transmitter.
The primary differences are in the data rate and signaling, as specified in the ISO/IEC specifications. For
more information, see Section 7.4.5, “100Base-TX Operation: Twisted-Pair Transmitter”.
7.5.12
10Base-T Operation: Twisted-Pair Receiver
The 10Base-T Twisted-Pair Receiver is functionally similar the 100Base-TX Twisted-Pair Receiver. The
primary differences are in the data rate and signaling, as specified in the ISO/IEC specifications. For more
information, see Section 7.4.6, “100Base-TX Operation: Twisted-Pair Receiver”.
7.5.13
10Base-T Operation: Auto Polarity Correction
The ICS1893AF can sense and then automatically correct a signal polarity that is reversed on its
Twisted-Pair Receiver inputs. A signal polarity reversal occurs when the input signals on an ICS1893AF’s
TP_RXP and TP_RXN pins are crossed or swapped (a problem that can occur during network installation
or wiring).
The ICS1893AF accomplishes reversed signal polarity detection and correction by examining the signal
polarity of the Normal Link Pulses (NLPs). In 10Base-T mode, an ICS1893AF transmits and receives NLPs
when its link is in the Idle state. In 100Base-TX mode, an ICS1893AF transmits and receives NLPs during
Auto-Negotiation. An STA can control this feature using the 10Base-T Operations Register bit 18.3, the
Auto Polarity-Inhibit bit. When this bit is logic:
Zero, the ICS1893AF automatically senses and corrects a reversed or inverted signal polarity on its
Twisted-Pair Receive pins (TP_RXP and TP_RXN).
One, the ICS1893AF disables this feature.
When an ICS1893AF detects a reversed signal polarity on its Twisted-Pair Receiver pins and the Auto
Polarity-Inhibit bit is also logic zero (enabled), the ICS1893AF (1) automatically corrects the data stream
and (2) sets its Polarity Reversed bit (bit 18.14) to logic one, to indicate to the STA that this situation exists.
Bit 18.14 is a latching high (LH) bit. (For more information on latching high and latching low bits, see
Note:
The Auto Polarity Correction Function is primarily a 10Base-T operation. However, it is part of the
Twisted-Pair Receiver and is operational during the 100Base-TX auto-negotiation process.
7.5.14
10Base-T Operation: Isolation Transformer
The 10Base-T Isolation Transformer operates the same as the 100Base-TX Isolation Transformer. In fact,
in a typical ICS1893AF application they are the same unit. For more information, see Section 7.4.8,
