ADIN1100BCPZ

Overview

The ADIN1100BCPZ is a robust, industrial-grade, low-power single-port 10BASE-T1L Ethernet PHY compliant with IEEE 802.3cg-2019. It supports cable reaches up to 1700 meters using 1.0 V p-p or 2.4 V p-p transmit levels. Power consumption is 39 mW in dual-supply 1.0 V p-p mode and 109 mW in single-supply 2.4 V p-p mode. The device operates from single or dual supplies of 1.8 V or 3.3 V, featuring integrated power supply monitoring, POR, and comprehensive EMC immunity including ±4 kV EFT and ±8 kV air discharge ESD.

Feature Summary

• Supports 1.0 V p-p and 2.4 V p-p transmit voltage levels for flexible cable reach optimization.
• Integrates Time Domain Reflectometry (TDR) for cable fault detection and link quality monitoring via Mean Squared Error (MSE).
• Provides MII, RMII, and RGMII MAC interface options with unmanaged pin-strapping configuration capabilities.
• Features high electromagnetic compatibility with IEC 61000-4-4 EFT (±4 kV), surge (±4 kV), and radiated immunity standards.

Applications

• Process control systems requiring long-reach industrial Ethernet connectivity.
• Factory automation networks utilizing Single Pair Ethernet (SPE).
• Building automation infrastructure with intrinsic safety requirements.
• Field instruments and switches deployed in harsh industrial environments.

Procurement Notes

Verify the specific suffix BC indicates the extended temperature range (-40°C to +105°C) as defined in the Analog Devices ordering guide. Confirm package type CP corresponds to the 40-lead, 6 mm × 6 mm LFCSP. Ensure design compliance with the required external crystal specifications (25 MHz) or clock input parameters for the selected MAC interface mode.

Selection Notes

Select this component for applications demanding low power consumption alongside long cable distances up to 1700 meters. Choose the 1.0 V p-p mode for ultra-low power scenarios (39 mW) and 2.4 V p-p mode for maximum reach. Ensure the host system supports the required MAC interface (MII/RMII/RGMII) and provides appropriate voltage rails (1.8 V/3.3 V) for AVDD and VDDIO domains.

Part Context

The ADIN1100 belongs to Analog Devices' portfolio of robust, industrial Single Pair Ethernet transceivers designed for 10 Mbps communication. It serves as a key enabler for IIoT and fieldbus replacement architectures, offering a compact solution that integrates PHY analog circuitry, management registers, and MAC logic into a small LFCSP package suitable for space-constrained industrial devices.

Replacement Considerations

Publicly confirmed substitutes include the ADIN1110, which adds MAC functionality, and the ADIN2111, a multi-port switch solution. For direct PHY replacement, verify compatibility with Texas Instruments DP83TD510E or Microchip LAN8670, ensuring differences in MAC interface support and power supply configurations are addressed in the redesign.

FAQ

How does the ADIN1100 handle cable fault detection?

The device integrates a Time Domain Reflectometry (TDR) engine that can detect cable faults and measure distance to fault, providing diagnostic information through the MDIO interface.

What transmit voltage levels are supported?

The ADIN1100 supports both 1.0 V p-p and 2.4 V p-p transmit levels. The 1.0 V p-p level is typically used with a 1.8 V supply for lower power, while 2.4 V p-p requires a 3.3 V supply for extended reach.

Can the ADIN1100 operate without a microcontroller?

Yes, it supports unmanaged configuration via hardware pin strapping, allowing basic link establishment without software intervention, though managed operation via MDIO is recommended for diagnostics.
