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
