ADIN2111BCPZ

Overview

The ADIN2111BCPZ-R7 is a low-power, two-port Ethernet switch IC integrating 10BASE-T1L PHYs compliant with IEEE 802.3cg-2019. It supports cable reach up to 1700 meters and operates at 10 Mbps. Power consumption is 77 mW (dual supply, 1.0 V p-p) or 90 mW (single supply). The device features a 4-wire SPI interface configurable for OPEN Alliance or generic modes, supporting cut-through or store-and-forward switching. It includes 28 kB buffer memory, 16 MAC address filters, high/low priority queues, and IEEE 1588 timestamping. Operating voltage ranges from 1.71 V to 3.46 V across AVDD_H, AVDD_L, DVDD_1P1, and VDDIO domains.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature range. Confirm availability status directly with authorized distributors as stock levels fluctuate. Ensure the component meets required electromagnetic compatibility standards for the intended deployment environment before finalizing procurement.

Selection Notes

Select this component for applications requiring low-complexity, energy-efficient Ethernet switching over single pair cables. Evaluate power supply requirements carefully, noting support for single, dual, or triple supply configurations depending on transmit amplitude needs. Consider the 48-lead LFCSP package dimensions for PCB layout constraints and verify thermal dissipation capabilities within the operating temperature range.
