3.3-V 10Base-T/100Base-TX Integrated PHYceiver™
General
The ICS1893AF is a lower cost, re-packaged version of the
ICS1893Y-10. The ICS1893AF is a fully integrated, Physical
Layer device (PHY) that is compliant with both the 10Base-T
and 100Base-TX CSMA/CD Ethernet Standard, ISO/IEC
8802-3. The ICS1893AF uses the same proven silicon as
the ICS1893Y-10 but offers a lower cost solution by using a
lower cost 300 mil. 48-lead SSOP package.
The ICS1893AF uses the same twisted-pair transmit and
receive circuits as the ICS1893Y-10, and the same
recommended board layout techniques apply to the
ICS1893AF.
The ICS1893AF is intended for Node applications using the
standard MII interface to the MAC.
All differences in the ICS1893AF / ICS1893Y-10 Feature Set
are listed in the Comparison Table on page 14.
