1 / 12 page  Integrated Circuit Systems, Inc. ICS1893AF Product Brief Page 1 Document Revision: 5 April 2002 3.3V 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 300mil 48-lead SSOP package. All parametric specifications and timing diagrams for the ICS1893Y-10 apply to the ICS1893AF. Refer to the 1893 Data Sheet for detailed specifications and timings. 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 changes are listed in the ICS1893AF / ICS1893Y-10 Feature Set Comparison Table on page 2. ICS1893AF Features • Single 3.3V power supply • Supports category 5 cables with attenuation in excess of 24dB at 100 MHz across a temperature range from - 5º to +85º C. • DSP-based baseline wander correction to virtually eliminate killer packets across temperature range of -5º to +85º C. • Low-power, 0.35-micron CMOS (typically 400mW) • Single-chip, fully integrated PHY provides PCS, PMA, PMD and AUTONEG Sublayers of the IEEE Std. • 10Base-T and 100Base-TX IEEE 8802-3 compliant • Clock or crystal supported. • Media Independent Interface (MII) supported. • Managed or Unmanaged Applications • 10M or 100M Half and Full Duplex Modes • Auto-Negotiation with Next Page. Parallel detection for Legacy products. • Fully-integrated, DSP-based PMD includes: - Adaptive equalization and baseline wander correction - Transmit wave shaping and stream cipher scrambler - MLT-3 encoder and NRZ/NRZI encoder • Highly configurable supports: - Node applications, managed or unmanaged - 10M or 100M half and full duplex modes • Loopback mode for Diagnostic Functions • Small footprint 48-lead 300mil SSOP package.
