3.3-V 10Base-T/100Base-TX Integrated PHYceiver
General
The ICS1893CF 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 ICS1893CF is intended for MII, Node applications that
require the Auto-MDIX feature that automatically corrects
crossover errors in plant wiring.
The ICS1893CF 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 ICS-patented
technology, the ICS1893CF can virtually eliminate errors from
killer packets.
The ICS1893CF provides a Serial-Management Interface for
exchanging command and status information with a
Station-Management (STA) entity. The ICS1893CF
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.
The ICS1893CF is available in a 300-mil 48-lead SSOP
package. The ICS1893CF shares the same proven
performance circuitry with the ICS1893BF and is a pin-for-pin
replacement of the 1893BF.
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 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.
10Base-T and 100Base-TX IEEE 8802.3 compliant
Single 3.3V power supply
Highly configurable, supports:
– Media Independent Interface (MII)
– Auto-Negotiation with Parallel detection
– Node applications, managed or unmanaged
– 10M or 100M full and half-duplex modes
