10BASE-T/100BASE-TX INTEGRATED PHYCEIVER WITH RMII INTERFACE
ICS1894-32
Description
The ICS1894-32 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, ISO/IEC
8802.3. It is intended for RMII/MII Node applications and
includes the Auto-MDIX feature that automatically corrects
crossover errors in plant wiring.
The ICS1894-32 incorporates Digital-Signal Processing
(DSP) control in its Physical-Medium Dependent (PMD)
sub-layer. 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 100MHz.
The ICS1894-32 provides a Serial-Management Interface
for exchanging command and status information with a
Station-Management (STA) entity. The ICS1894-32
Media-Dependent Interface (MDI) can be configured to
provide full-duplex operation at data rates of 10 Mb/s or
100Mb/s.
In addition, the ICS1894-32 includes a programmable LED
and interrupt output function. The LED outputs can be
configured through registers to indicate the occurance of
certain events such as LINK, COLLISION, ACTIVITY, etc.
The purpose of the programmable interrupt output is to
notify the PHY controller device immediately when a certain
event happens instead of having the PHY controller
continuously poll the PHY. The events that could be used to
generate interrupts are: receiver error, Jabber, page
received, parallel detect fault, link partner acknowledge, link
status change, auto-negotiation complete, remote fault,
collision, etc.
The ICS1894-32 has deep power modes that can result in
significant power savings when the link is broken.
Applications:
NIC cards, PC motherboards, switches,
routers, DSL and cable modems, game machines, printers,
network connected appliances, and industrial equipment.
Features
Supports category 5 cables and above with attenuation in
excess of 24dB at 100 MHz.
Single-chip, fully integrated PHY provides PCS, PMA,
PMD, and AUTONEG sub layers functions of IEEE
standard.
