1893Y-10LFT

Overview

The ICS1893Y-10LFT is a fully integrated, low-power Physical Layer device (PHY) compliant with IEEE 802.3 standards for 10Base-T and 100Base-TX Ethernet. It operates on a single 3.3-V power supply and consumes typically 400 mW using 0.35-micron CMOS technology. The device supports Category 5 cables with attenuation exceeding 24 dB at 100 MHz through DSP-based baseline wander correction and adaptive equalization. It provides PCS, PMA, PMD, and Auto-Negotiation sublayers in a small 64-pin Thin Quad Flat Pack (TQFP) package.

Feature Summary

• Fully integrated PHY supporting 10Base-T and 100Base-TX standards
• DSP-based PMD with adaptive equalization and baseline wander correction
• Configurable MAC/Repeater interface including MII, Symbol, and Serial modes
• Auto-negotiation with Next Page capabilities and parallel detection

Applications

• Node applications using standard MII interface to the MAC
• Managed or unmanaged switch applications
• Repeater applications requiring half- or full-duplex operation

Procurement Notes

Verify the component datasheet revision against the manufacturer's latest release to ensure accuracy of all electrical parameters and pin configurations. Confirm that the lead-free suffix 'LF' matches the specific environmental compliance requirements of the target assembly process. Cross-reference the package type and temperature range specifications with the design constraints before finalizing procurement orders.

Selection Notes

Select this component when a fully integrated, low-power solution for 10/100 Mbps Ethernet is required. Ensure the system design accommodates a single 3.3-V power supply and utilizes a 64-pin TQFP footprint. Verify compatibility with the intended MAC interface mode, whether Media Independent Interface, Symbol Interface, or 10M Serial Interface, based on the specific application architecture.

Part Context

The ICS1893Y-10 is part of the PHYceiver family of high-speed physical layer transceivers from Integrated Circuit Systems, Inc., which was later acquired by Renesas Electronics Corporation. This specific model represents a fully integrated solution designed for cost-effective implementation of Ethernet connectivity in network infrastructure and end-user devices.

Replacement Considerations

The ICS1893AF is documented as a lower-cost, re-packaged version of the ICS1893Y-10 utilizing a 48-lead SSOP package instead of the 64-pin TQFP. Designers must account for the pinout differences and package size reduction when considering this alternative.
