1893BY-10LF

Overview

The ICS1893BY-10 is a low-power, fully integrated physical-layer device (PHY) compliant with ISO/IEC 10Base-T and 100Base-TX Ethernet standards. It operates on a single 3.3-V power supply and utilizes 0.35-micron CMOS technology, consuming typically 400 mW during operation and 21 mW in power-down mode. The device supports unshielded twisted-pair Category 5 cables with attenuation exceeding 24 dB at 100 MHz. It features an integrated DSP-based PMD sublayer providing adaptive equalization and baseline wander correction. The MAC interface is configurable as a 10M or 100M Media Independent Interface (MII), a 100M Symbol Interface, or a 10M Serial Interface.

Feature Summary

• Integrated digital signal processing for adaptive equalization and baseline wander correction to eliminate errors from killer packets.
• Configurable MAC/Repeater interface supporting MII, 100M Symbol, and 10M Serial modes.
• Auto-MDI/MDIX crossover correction capability for automatic wiring error adjustment.
• Supports managed and unmanaged applications with auto-negotiation and Next Page capabilities.

Applications

• Node applications requiring Auto-MDI/MDIX functionality
• Managed and unmanaged switch designs
• Repeater implementations
