Ethernet Controllers | NCN26000
概览
The NCN26000 device is an IEEE 802.3cg compliant Ethernet Transceiver (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. The NCN26000 communicates to existing half−duplex 10 Mb/s capable Ethernet MAC controllers via a standard MII interface.

- Enhanced Noise Immunity Mode:
- ENI extends the noise immunity to values well above the IEEE T1S standard
- Allows the NCN26000 to withstand worst-case DPI and BCI immunity tests
- Significantly improves the network reach when enabled, almost 2X better than competition
- Unique to onsemi's 10BASE-T1S devices - Lowest Line Pin Capacitance:
- Best-in-class line pin capacitance allows for the highest number of nodes per segment.
- The NCN26000 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 NCNS26000 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 NCN26000 - 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 - Supports IEEE802.3 CSMA/CD Collision Detection:
- PLCA mode will default to CSMA/CD collision detection, if needed
