The ADIN1140 is a low power, high performance, single port 10BASE-T1S MAC-PHY designed for multidrop Ethernet connectivity applications.
The PHY complies with the IEEE 802.3™-2022 Ethernet standard for 10Mbps single-pair Ethernet. For point-to-point (half-duplex) configurations, the standard specifies up to 15m, but the ADIN1140 has been tested up to 200m. For multidrop configurations, the standard allows up to at least 8 nodes over 25m, while the ADIN1140 has been validated in setups with more than 40 nodes.
Physical layer collision avoidance (PLCA) is supported for improving latency and throughput performance in a half-duplex communication system. The PLCA block includes PLCA coordinator mode, burst mode, and precedence mode. Multiple PLCA IDs reduce latency as certain nodes can be prioritized using more than one transmit opportunity within a PLCA cycle.
OPEN Alliance TC10/TC14 features include:
- Sleep/Wake-up
- Topology discovery
- Advanced diagnostics including dynamic channel quality (DCQ) and signal quality index (SQI)
The ADIN1140 contains an integrated media access control (MAC) interface with 16 MAC address filters. It also supports VLAN and EtherType filtering.
