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
