ADIN2111CCPZ

Overview

The ADIN2111CCPZ is a low-complexity, two-port Ethernet switch with integrated 10BASE-T1L PHYs compliant with IEEE 802.3cg-2019. It supports cable reaches up to 1700 meters and features an internal switch with SPI interface supporting OPEN Alliance MACPHY SPI. The device includes 16 MAC address filters, high/low priority queues with a 28 kB buffer, and cut-through or store-and-forward operation. It offers IEEE 1588 timestamp support, statistic counters, and diagnostics including TDR cable fault detection. Power consumption is 77 mW at 1.0 V p-p transmit level with dual supply (1.8 V analog/digital, 1.1 V core). It operates on single or dual supplies (1.8 V or 3.3 V) in industrial (-40°C to +85°C) or extended (-40°C to +105°C) temperature ranges within a 48-lead LFCSP package.

Feature Summary

• Integrates a media access control (MAC) and switch for direct connectivity via SPI.
• Supports flexible network topologies including line, daisy-chain, and ring configurations.
• Includes comprehensive on-chip diagnostics such as Time Domain Reflectometry (TDR) and link quality monitoring.
• Compliant with IEC electromagnetic compatibility standards for harsh industrial environments.

Applications

• Building automation and fire safety systems
• Factory automation networks
• Condition monitoring and machine connectivity

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type, temperature range, and lead-free status. Ensure the component matches the required voltage domains and interface protocols for your system design. Cross-reference the part number with official Analog Devices distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component for applications requiring long-reach single-pair Ethernet connectivity up to 1700 meters. Choose based on the required operating temperature range (industrial vs. extended) and power supply configuration (single vs. dual). Ensure the host controller supports the necessary SPI mode (OPEN Alliance or generic) and that the PCB layout accommodates the 48-lead LFCSP package constraints.

Part Context

The ADIN2111 belongs to Analog Devices' family of 10BASE-T1L transceivers designed for industrial Ethernet. It simplifies network design by integrating the PHY and switch functions into a single low-power chip. This integration reduces board space and component count compared to discrete solutions, making it suitable for compact industrial sensors and actuators requiring robust, long-distance communication.

Replacement Considerations

Check for updated revisions of the ADIN2111 series. Verify pinout compatibility if substituting with other 10BASE-T1L switches from different manufacturers. Ensure functional equivalence regarding SPI register maps and diagnostic capabilities when considering alternative parts.
