1893Y-10LF

Overview

The ICS1893Y-10 is a fully integrated Physical Layer device compliant with IEEE 802.3 10Base-T and 100Base-TX standards. It operates on a single 3.3-V power supply with typical power consumption of 400 mW using 0.35-micron CMOS technology. The chip supports Category 5 cables with attenuation exceeding 24 dB at 100 MHz via DSP-based baseline wander correction. It provides PCS, PMA, PMD, and Auto-Negotiation sublayers in a 64-pin TQFP package.

Feature Summary

• Fully integrated PHY supporting 10Base-T and 100Base-TX Ethernet standards
• DSP-based PMD with adaptive equalization and baseline wander correction
• Configurable MAC/Repeater interface including MII, Symbol, and Serial modes
• Supports managed and unmanaged node, repeater, and switch applications

Applications

• Node applications using standard MII interface to the MAC
• Managed or unmanaged network switch implementations
• Repeater designs requiring 10M or 100M half/full duplex operation

Procurement Notes

Verify the specific revision level against the manufacturer's latest documentation before implementation. Confirm that the lead-free designation aligns with current environmental compliance requirements for your target market. Ensure the 64-pin TQFP footprint matches your PCB layout specifications exactly.

Selection Notes

Select this component when a low-power, single-chip solution for 10/100 Mbps Ethernet is required. It is suitable for designs needing flexible interface options such as MII or serial connections. Consider its DSP capabilities if cable attenuation compensation is necessary for long-distance twisted-pair links.

Part Context

This device belongs to the PHYceiver family of high-speed physical layer transceivers. It represents an evolution of the ICS1892 architecture, offering enhanced integration for Fast Ethernet applications. The part was originally manufactured by Integrated Circuit Systems, Inc., which later became part of Renesas Electronics Corporation.

Replacement Considerations

The ICS1893AF is a lower-cost variant utilizing a 48-lead SSOP package but shares the same silicon and functional feature set.
