Product Brief
ICS1893AF
Typical ICS1893AF Applications
The ICS1893AF is configured for the majority of single Phy Ethernet applications. These applications include
Network Interface Cards, PC Motherboards, Printers, ACR Riser cards, Set top Boxes, and Game machines.
Virtually any single Phy application utilizing the standard IEEE MII interface can use the ICS1893AF. The
ICS1893AF offers the same high performance at a lower cost.

The following bullet items describe ICS1893AF pin differences and how they affect the
application:
• The ICS1893AF is hardwired for the predominate board application used in the vast majority of single
Phy applications
o Hardwired for Node configuration (NOD/REP pin removed, tied internally to VSS). Node
configuration enables the 10M SQE test default setting and causes CRS to be asserted for either
transmit or receive activity in half duplex, or for just receive activity when in full duplex.
o Hardwired for Software mode (HW/SW pin removed, tied internally to VDD).
o Hardwired for MII interface only. (SI/MII pin removed, tied internally to VDD) In this configuration
the 10baseT serial and 100baseTX 5 bit symbol interfaces are NOT supported. Applications
requiring these interfaces should use ICS1893Y-10.
• In the software control configuration the 10/100, DPXSEL and ANSEL pins are outputs.
o DPXEL pin is not brought out.
o ANSEL pin is not brought out.
o 10/100 pin is brought out to indicate 100M operation. Some applications use this output to drive
an LED indicating 100M operation.
