General
The ICS1893 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. The ICS1893 architecture is based on the ICS1892. The ICS1893 supports managed or unmanaged node, repeater, and switch applications.

FEATUREs
• Supports category 5 cables with attenuation in excess of 24 dB at 100 MHz across a temperature range from -5°to +85°C
• DSP-based baseline wander correction to virtually eliminate killer packets across temperature range of from -5°to +85°C
• Low-power, 0.35-micron CMOS (typically 400 mW)
• Single 3.3-V power supply.
• Single-chip, fully integrated PHY provides PCS, PMA, PMD, and AUTONEG sublayers of IEEE standard
• 10Base-T and 100Base-TX IEEE 802.3 compliant
• 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 design supports:
    – Node, repeater, and switch applications
    – Managed and unmanaged applications
    – 10M or 100M half- and full-duplex modes
    – Parallel detection
    – Auto-negotiation, with Next Page capabilities
• MAC/Repeater Interface can be configured as:
    – 10M or 100M Media Independent Interface
    – 100M Symbol Interface (bypasses the PCS)
    – 10M 7-wire Serial Interface
• Small Footprint 64-pin Thin Quad Flat Pack (TQFP)
