Ethernet PHY for industrial 10/100 links
The Analog Devices ADIN1200CCP32Z-R7 is an IEEE 802.3-compliant Ethernet transceiver (PHY) supporting 10 Mbps and 100 Mbps data rates over MII and RMII interfaces. It handles both full and half duplex operation, with four driver and four receiver channels on a single die. The part is packaged in a 32-lead LFCSP (5x5 mm) with an exposed pad for thermal management, and it operates across the industrial temperature range of -40°C to 105°C.
Supply rails and power tree planning
This PHY requires three separate supply domains: a 1.71 V to 1.89 V core rail, a 2.25 V to 2.75 V I/O rail, and a 3.14 V to 3.46 V analog rail.
Industrial temperature and package handling
Rated for -40°C to 105°C ambient, this PHY suits outdoor telecom cabinets, factory-floor Ethernet switches, and motor-drive communication ports where the enclosure sees elevated temperatures. The 32-LFCSP with exposed pad requires a proper thermal via pattern under the pad to keep junction temperature within limits at 105°C ambient. The exposed pad is also the ground return for the analog supply — poor solder coverage here shows up as increased bit-error rate.
Driver/receiver count and duplex
With four drivers and four receivers, this is a multi-port PHY intended for applications like a four-port switch or a multi-interface industrial gateway. Full and half duplex support means it can connect to both switched networks (full duplex) and legacy hubs or shared-media segments (half duplex). The MII and RMII interfaces give flexibility in connecting to host controllers with either a 4-bit or 2-bit data bus.
Lifecycle and compliance
It is ROHS3 compliant, which covers the latest EU exemption updates. No LTB window or successor part has been announced — this is a safe choice for new designs requiring a 10/100 industrial PHY.
