Ethernet Controllers | NCN26010
Ethernet Controller, 10 Mb/s, Single-Pair, MAC + PHY, 802.3cg, 10BASE−T1S Compliant
概览
The NCN26010 device is an IEEE 802.3cg compliant Ethernet Transceiver including a Media Access Controller (MAC), a PLCA Reconciliation Sublayer (RS) and a 10BASE−T1S PHY designed for industrial multi−drop Ethernet. It provides all physical layer functions needed to transmit and receive data over a single unshielded twisted pair. NCN26010 communicates to host MCUs via Open Alliance MACPHY SPI protocol.

特性
- Enhanced Noise Immunity Mode:
- ENI extends the noise immunity to values well above the IEEE T1S standard
- Allows the NCN26010 to withstand worst-case DPI and BCI immunity tests
- Significantly improves the network reach when enabled, almost 2X better than competition
- Unique to NCN26010 - Lowest Line Pin Capacitance:
- Best-in-class line pin capacitance allows for the highest number of nodes per segment.
- The NCN26010 supports up to 40 nodes on a 25-meter segment, well above the IEEE minimum standard
- Lowers cabling, connector, and installation costs - Collision Detection Masking:
- Masking detected collisions allows operation in noisy conditions
- Prevents false collision detection in high-noise environments
- When used in conjunction with ENI, the NCNS26010 has unparalleled noise tolerance - PLCA Precedence Mode:
- Lower PLCA ID's get precedence over higher ones
- Provides arbitration similar to CAN: The Coordinator (i.e., the head node) sends a new beacon once any station transmits
- Unique to NCN26010 - Physical Layer collision avoidance PLCA:
- Allows higher throughput in multi-drop topologies - Two Configurable Digital Outputs that can Drive Low Current LEDs:
- Supports systems where up to two LEDs can provide status indicators - Open Alliance Compatible SPI Interface:
- Conforms to Open Alliance TC6 specs for Configuration and Data Frames to Host MCUs - MAC Address Filtering:
- By filtering frames based on the destination address, Ethernet frames not intended for a certain node are not processed by the host, thus reducing the load
- The MAC will see the frame, process the address, drop it based on the filter criteria, and the host will not need to handle it - Supports IEEE802.3 CSMA/CD Collision Detection:
- PLCA mode will default to CSMA/CD collision detection, if needed
