6.4.7 100Base-TX Operation: Auto Polarity Correction
6.4.8 100Base-TX Operation: Isolation Transformer
ICS1893Y-10 Rev F 1/20/04
The ICS1893Y-10 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 the TP_RXP and
TP_RXN pins are crossed or swapped (a problem that can occur during network installation or wiring). This
function is primarily a 10Base-T function, however, it is also active during Auto-Negotiation. For more
information on the 10Base-T Auto Polarity Correction, see
Polarity Correction”
The ICS1893Y-10 interfaces with a medium through isolation transformers. The PHY requires two isolation
transformers: one for its Twisted-Pair Transmitter and the other for its Twisted-Pair Receiver. These
isolation transformers provide both physical isolation as well as the means for coupling a signal between
the ICS1893Y-10 and the medium for both 10Base-T and 100Base-TX operations.
