1893AFLF

Overview

The Renesas Electronics Corporation 1893AFLF is a fully integrated Physical Layer device (PHY) compliant with IEEE 802.3 standards for 10Base-T and 100Base-TX Ethernet networks. Operating on a single 3.3V power supply, this component integrates the PCS, PMA, PMD, and Auto-Negotiation sublayers into a single chip. It utilizes a low-power 0.35-micron CMOS process, typically consuming 400 mW. The device supports both half-duplex and full-duplex modes at 10M or 100M speeds, featuring DSP-based baseline wander correction and adaptive equalization to ensure signal integrity over Category 5 cables.

Feature Summary

• Integrates all IEEE 802.3 physical layer sublayers including PCS, PMA, PMD, and Auto-Negotiation functions.
• Incorporates DSP-based baseline wander correction and adaptive equalization to mitigate signal degradation.
• Supports Media Independent Interface (MII) for flexible connection to MAC controllers.
• Includes diagnostic capabilities such as loopback mode for system verification.

Applications

• 10Base-T and 100Base-TX network interface implementations
• Managed and unmanaged Ethernet switch designs
• Industrial control systems requiring reliable wired connectivity

Procurement Notes

Verify component authenticity through authorized channels due to discontinued status. Confirm RoHS compliance details via official documentation before integration. Ensure storage conditions meet moisture sensitivity level requirements to prevent package damage during assembly.

Selection Notes

Select this component for applications requiring a cost-effective, single-chip PHY solution for standard Ethernet connections. Consider the 48-lead SSOP package constraints regarding board space. Verify compatibility with the target system's voltage levels and MII interface requirements prior to design finalization.

Part Context

This part belongs to the Integrated Device Technology (IDT) product line, now part of Renesas Electronics. It serves as a lower-cost alternative to the ICS1893Y-10, utilizing the same silicon but packaged in a more economical 300 mil SSOP format. It addresses the need for compact, low-power Ethernet connectivity in embedded systems.

Replacement Considerations

The ICS1893AGI is a documented similar part number within the same family. Verify pinout and feature parity against the specific datasheet revision before substitution. No other direct cross-references are confirmed in public documentation.
