ICS1893Y-10

Controllers Overview

The ICS1893Y-10 is a fully integrated, low-power physical-layer device (PHY) compliant with ISO/IEC 10Base-T and 100Base-TX CSMA/CD Ethernet standards. It operates on a single 3.3-V power supply and utilizes 0.35-micron CMOS technology, consuming typically 400 mW. The device supports data rates of 10 MHz or 100 MHz in half- or full-duplex modes. It incorporates DSP-based baseline wander correction to eliminate killer packets across a temperature range of -5°C to +85°C. The PHY provides PCS, PMA, PMD, and AUTONEG sublayers within a small footprint 64-pin Thin Quad Flat Pack (TQFP).

Controllers Feature Summary

• Supports Category 5 cables with attenuation exceeding 24 dB at 100 MHz.
• Integrates adaptive equalization and baseline wander correction via DSP.
• Configurable MAC/Repeater interface supporting MII, Symbol Interface, and Serial Interface.
• Enables auto-negotiation with Next Page capabilities for link partner selection.

Controllers Applications

• Managed and unmanaged node applications
• Repeater implementations
• Switch designs

Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature range. Confirm that the component meets RoHS requirements if applicable to the target assembly process. Ensure the design accounts for the 64-pin TQFP footprint dimensions during PCB layout.

Controllers Selection Notes

Select this component for designs requiring a single-chip solution for 10/100 Mbps Ethernet over twisted pair. Consider the configurable interface options when integrating with different MAC controllers. Evaluate the power consumption specifications against system thermal constraints.

Controllers Part Context

The ICS1893 series represents an enhanced version of earlier PHY devices, incorporating digital signal processing directly into the Physical Medium Dependent sublayer. This integration allows for robust performance on standard cabling without external equalization components. The Y-10 designation typically indicates a specific commercial temperature range variant within the product family.

Controllers Replacement Considerations

The ICS1893AF is documented as a lower-cost, re-packaged version using the same silicon but housed in a 48-lead SSOP package. Verify pin compatibility and mechanical dimensions before substituting, as the package change requires board layout adjustments.
