ICS1893BY-10  
3.3-V 10Base-T/100Base-TX Integrated PHYceiver™  
General  
Features  
The ICS1893BY-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 ICS1893BY-10  
supports managed or unmanaged node, repeater, and  
switch applications.  
Supports category 5 cables with attenuation in excess of  
24 dB at 100 MHz  
Fully integrated, DSP-based PMD includes:  
– Adaptive equalization and baseline wander correction  
– Transmit wave shaping and stream cipher scrambler  
– MLT-3 encoder and NRZ/NRZI encoder  
Low-power, 0.35-micron CMOS (typically 400 mW)  
Power-down mode typically 21mW  
Single 3.3-V power supply.  
The ICS1893BY-10 is intended for MII, Node applications  
that require the Auto-MIDIX feature that automatically  
corrects crossover errors in plant wiring.  
Single-chip, fully integrated PHY provides PCS, PMA,  
PMD, and AUTONEG sublayers of IEEE standard  
The ICS1893BY-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 ICS1893BY-10 can virtually eliminate errors  
from killer packets.  
10Base-T and 100Base-TX IEEE 802.3 compliant  
Highly configurable design supports:  
– Node, repeater, and switch applications  
– Managed and unmanaged applications  
– 10M or 100M half- and full-duplex modes  
– Parallel detection  
– Auto-negotiation, with Next Page capabilities  
– Auto-MDI/MDIX crossover correction  
The ICS1893BY-10 provides a Serial Management Interface  
for exchanging command and status information with a  
Station Management (STA) entity.  
MAC/Repeater Interface can be configured as:  
– 10M or 100M Media Independent Interface  
– 100M Symbol Interface (bypasses the PCS)  
– 10M 7-wire Serial Interface  
The ICS1893BY-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  
register settings) or automatically (using the  
Auto-Negotiation features). When the ICS1893BY-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.
