ICS1893BF Data Sheet Rev. F - Release
Copyright 2009, IDT, Inc.
All rights reserved.
An ICS1893BF SQE Test Function is:
Enabled only when all the following conditions are true:
– The ICS1893BF is in node mode.
– The ICS1893BF is in half-duplex mode.
– The ICS1893BF has a valid link.
– The 10Base-T Operations Register’s SQE Test Inhibit bit (bit 18.2) is logic zero (the default).
– The ICS1893BF TX_EN signal has transitioned from asserted (high) to de-asserted (low).
Disabled whenever any of the following are true:
– The ICS1893BF is in full-duplex mode.
– The ICS1893BF detects a link failure.
– The ICS1893BF SQE Test Inhibit bit (bit 18.2) in the 10Base-T Operations Register is logic one. [This
bit provides the Station Management entity (STA) with the ability to disable the SQE Test function.]
Note:
1. In 10Base-T mode, a bit time has a typical duration of 100 ns.
2. The SQE Test also has the name 10Base-T Heartbeat. For details on the SQE waveforms, see Section
6.5.11 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 6.4.5, “100Base-TX Operation: Twisted-Pair Transmitter”.
6.5.12 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 6.4.6, “100Base-TX Operation: Twisted-Pair Receiver”.
6.5.13 10Base-T Operation: Auto Polarity Correction
The ICS1893BF 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 ICS1893BF’s
TP_RXP and TP_RXN pins are crossed or swapped (a problem that can occur during network installation
or wiring).
The ICS1893BF accomplishes reversed signal polarity detection and correction by examining the signal
polarity of the Normal Link Pulses (NLPs). In 10Base-T mode, an ICS1893BF transmits and receives NLPs
when its link is in the Idle state. In 100Base-TX mode, an ICS1893BF 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 ICS1893BF automatically senses and corrects a reversed or inverted signal polarity on its
Twisted-Pair Receive pins (TP_RXP and TP_RXN).
One, the ICS1893BF disables this feature.
