10BASE-T/100BASE-TX INTEGRATED PHYCEIVER WITH RMII INTERFACE
ICS1894-40
IDT / ICS 10BASE-T/100BASE-TX INTEGRATED PHYCEIVER WITH RMII INTERFACE 1
ICS1894-40
REV C 092909
Description
The ICS1894-40 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.
The ICS1894-40 is intended for MII, Node applications that
require the Auto-MDIX feature that automatically corrects
crossover errors in plant wiring.
The ICS1894-40 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. With this
IDT-patented technology, the ICS1894-40 can virtually
eliminate errors from killer packets.
The ICS1894-40 provides a Serial-Management Interface
for exchanging command and status information with a
Station-Management (STA) entity. The ICS1894-40
Media-Dependent Interface (MDI) can be configured to
provide either half- or full-duplex operation at data rates of
10 Mb/s or 100Mb/s.
In addition, the ICS1894-40 includes a programmable
interupt output function. This function consists of a digital
output pin, an interrupt control register, a set of interrupt
status register bits and a corresponding set of interrupt
enable bits, and a pre-defined set of events which can be
assigned as one of the interrupt sources. The purpose of
this function is to notify the host of this PHY device when
certain event happens via interrupt (the logic level on
interrupt output pin going low or going high) instead of
polling by the host. 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
Applications: NIC cards, PC motherboards, switches,
routers, DSL and cable modems, game machines, printers,
network connected appliances, and industrial equipment.
