ICS1893AFI

Controllers Overview

The ICS1893AFI is a fully integrated, low-power Physical Layer device (PHY) compliant with the 10Base-T and 100Base-TX CSMA/CD Ethernet standards. It utilizes a single 3.3V power supply and operates on a 0.35-micron CMOS process, consuming typically 400 mW. The component supports Category 5 cables with attenuation exceeding 24dB at 100 MHz through DSP-based baseline wander correction. It features an MII interface for MAC connection, supports both clock and crystal references, and includes Auto-Negotiation with parallel detection for legacy products.

Controllers Feature Summary

• Single-chip integration of PCS, PMA, PMD, and Auto-Negotiation sublayers
• DSP-based adaptive equalization and baseline wander correction
• Supports 10M or 100M half and full duplex modes
• Loopback mode for diagnostic functions

Controllers Applications

• Node applications using standard MII interface to MAC
• Managed or unmanaged network applications
• Low-cost re-packaged solutions utilizing proven silicon

Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature range. Confirm RoHS compliance status as required by project specifications. Ensure the source document matches the exact part number variant before procurement to avoid discrepancies in pinout or electrical characteristics.

Controllers Selection Notes

Select this component for designs requiring a cost-effective PHY solution that maintains compatibility with the ICS1893Y-10 silicon. It is suitable for applications where a smaller 48-lead SSOP footprint is preferred over larger packages. Ensure the design supports the required 3.3V supply voltage and accommodates the necessary twisted-pair transmit and receive circuits.

Controllers Part Context

The ICS1893AFI is a lower-cost, re-packaged version of the ICS1893Y-10. It shares the same proven silicon and twisted-pair transmit/receive circuits but utilizes a more economical 300 mil 48-lead SSOP package. Recommended board layout techniques remain identical to the original Y-10 variant.

Controllers Replacement Considerations

The ICS1893Y-10 serves as the primary functional equivalent, differing primarily in package dimensions.
