General
The ICS1893Y-10 is a low-power, physical-layer device
(PHY) that supports the ISO/IEC 10Base-T and 100Base-TX
Carrier-Sense Multiple Access/Collision Detection
(CSMA/CD) Ethernet standards. The ICS1893Y-10
architecture is based on the ICS1892. The ICS1893Y-10
supports managed or unmanaged node, repeater, and
switch applications.
The ICS1893Y-10 incorporates digital signal processing
(DSP) in its Physical Medium Dependent (PMD) sublayer.
As a result, it can transmit and receive data on unshielded
twisted-pair (UTP) category 5 cables with attenuation in
excess of 24 dB at 100 MHz. With this ICS-patented
technology, the ICS1893Y-10 can virtually eliminate errors
from killer packets.
The ICS1893Y-10 provides a Serial Management Interface
for exchanging command and status information with a
Station Management (STA) entity.
The ICS1893Y-10 Media Dependent Interface (MDI) can be
configured to provide either half- or full-duplex operation at
data rates of 10 MHz or 100 MHz. The MDI configuration
can be established manually (with input pins or control
r e g i s t e r s e t t i n g s ) o r a u t o m a t i c a l l y ( u s i n g t h e
Auto-Negotiation features). When the ICS1893Y-10
Auto-Negotiation sublayer is enabled, it exchanges
technology capability data with its remote link partner and
automatically selects the highest-performance operating
mode they have in common.

ICS1893Y-10 has the auto-negotiation process enabled and it is operating with a 10Base-T remote link partner, the ICS1893Y-10 monitors the link and automatically selects the 10Base-T operating mode – even though the remote link partner does not support auto-negotiation. This process, called parallel detection, is automatic and transparent to the remote link partner and allows the ICS1893Y-10 to function seamlessly with existing legacy network structures without any management intervention ...

Both the ICS1893Y-10 and the remote link partner substitute Fast Link Pulse (FLP) bursts in place of the Normal Link Pulses (NLPs). In each FLP burst, the ICS1893Y-10 transmits information on its technology capability through its Link Control Word, which includes link configuration and status data ...
