NCN26010数据手册ONSEMI中文资料规格书

描述 Description

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 Features

• 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
