ADIN1100BCPZ-R7

Overview

The ADIN1100BCPZ-R7 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 as low as 39 mW in dual-supply 1.0 V p-p mode and 11 mW in software power-down. The device integrates an Ethernet PHY core, analog circuitry, clock buffering, MDIO management interface, and MAC interfaces (MII, RMII, RGMII). It features diagnostics including TDR cable fault detection, link quality monitoring via MSE, and frame generation/checking.

Feature Summary

• Supports intrinsic safety applications for hazardous environments
• Integrated Time Domain Reflectometry (TDR) for cable fault detection
• Compliant with IEC 61000-4 EMC standards including EFT, ESD, and surge immunity
• Unmanaged configuration capability via hardware pin strapping

Applications

• Process control systems
• Factory automation networks
• Building automation infrastructure
• Field instruments and switches

Procurement Notes

Verify the specific suffix -R7 indicates tape and reel packaging when sourcing. Confirm that the BC grade corresponds to the extended temperature range of −40°C to +105°C as defined in the Analog Devices ordering guide. Ensure compatibility with the required MAC interface voltage levels (1.8 V, 2.5 V, or 3.3 V) for the target system design.

Selection Notes

Select this component for applications requiring long-reach single-pair Ethernet connectivity up to 1700 meters. Choose based on the required transmit amplitude: use the 1.0 V p-p mode for lower power consumption or the 2.4 V p-p mode for maximum reach. Ensure the host processor supports MII, RMII, or RGMII interfaces for data exchange. Verify thermal requirements for the 40-lead LFCSP package in enclosed industrial enclosures.

Part Context

The ADIN1100 belongs to Analog Devices' portfolio of industrial Ethernet solutions designed for IIoT and process automation. It serves as a physical layer transceiver for 10 Mbps Single Pair Ethernet (SPE), enabling simplified cabling in field devices. The device complements higher-level controllers by handling the physical signaling and link management functions required for robust industrial communication networks.

Replacement Considerations

No direct public substitutes are confirmed in the provided documentation. Designers should evaluate other 10BASE-T1L PHYs from manufacturers such as Texas Instruments or Microchip Technology if alternative sourcing is required, ensuring compatibility with existing MAC interfaces and EMC requirements.

FAQ
