General

The ICS1893BY-10 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 ICS1893BY-10 supports managed or unmanaged node, repeater, and switch applications.

Features

• Supports category 5 cables with attenuation in excess of 24 dB at 100 MHz

• Fully integrated, DSP-based PMD includes:

– Adaptive equalization and baseline wander correction

– MLT-3 encoder and NRZ/NRZI encoder

• Low-power, 0.35-micron CMOS (typically 400 mW)

• Power-down mode typically 21mW

• 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

• Highly configurable design supports:

– Node, repeater, and switch applications

– Managed and unmanaged applications
