ICS1893BF

Controllers Overview

The ICS1893BF is a low-power, fully integrated physical-layer device (PHY) compliant with IEEE 802.3 10Base-T and 100Base-TX standards. It operates on a single 3.3V supply and features a 48-lead SSOP package. The device supports Media Independent Interface (MII), Auto-Negotiation with parallel detection, and Auto-MDI/MDIX crossover correction. It incorporates DSP-based PMD functions including adaptive equalization and baseline-wander correction to support Category 5 cables with attenuation exceeding 24dB at 100MHz. Typical power consumption is 400mW in active mode and 21mW in power-down mode.

Controllers Feature Summary

• Fully integrated PHY providing PCS, PMA, PMD, and AUTONEG sublayers for 10/100 Ethernet.
• DSP-based Physical-Medium Dependent layer with adaptive equalization and baseline-wander correction.
• Supports Auto-MDI/MDIX crossover correction for automatic wiring error handling.
• Configurable for managed or unmanaged node applications with loopback diagnostic modes.

Controllers Applications

• Network Interface Cards (NIC)
• PC Motherboards
• Ethernet Switches and Routers
• DSL and Cable Modems

Controllers Procurement Notes

Verify component status as the ICS1893BF may be End-of-Life (EOL). Confirm availability of lead-free versions if required by environmental regulations. Check for parameter-equivalent replacements such as the 1893CFLFT from Renesas Electronics Corporation. Ensure the specific package variant matches design requirements, as pinouts differ from related models like the ICS1893AF.

Controllers Selection Notes

Select this component for designs requiring a single-chip solution for 10/100 Base-T/TX Ethernet connectivity. Ensure the system architecture supports the MII interface and 3.3V power domain. Consider the 48-pin SSOP footprint constraints during PCB layout. Verify that the application environment falls within the commercial temperature range specified for this package type.

Controllers Part Context

The ICS1893BF belongs to the PHYceiver™ series of integrated Ethernet PHY devices manufactured by Integrated Device Technology (IDT), now part of Renesas Electronics Corporation. It shares proven silicon performance with the ICS1893AF but utilizes a distinct 48-lead SSOP package. It is designed to replace discrete PHY solutions by integrating all necessary sublayers into a single chip.

Controllers Replacement Considerations

The 1893CFLFT is listed as a parameter-equivalent replacement. Note that the ICS1893BF is not a pin-for-pin replacement for the ICS1893AF; dual-footprint layouts are recommended for compatibility between these variants.

Controllers FAQ

Is the ICS1893BF a pin-compatible replacement for the ICS1893AF?

No, the datasheet explicitly states that the ICS1893BF is not a pin-for-pin replacement for the ICS1893AF. A dual-footprint layout is available to accommodate both devices.

What is the typical power consumption of the ICS1893BF?

The typical power consumption is 400 mW in normal operation and approximately 21 mW in Power-Down mode.

Does the ICS1893BF support Auto-MDI/MDIX?

Yes, the device includes an Auto-MDI/MDIX feature that automatically corrects crossover errors in plant wiring without manual configuration.
