NCN26000数据手册ONSEMI中文资料规格书

描述 Description

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.

特性 Features

• 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
