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.

Features

• 10BASE−T1S − IEEE 802.3cg Compliant

• Data Rate of 10 Mb/s, Half−Duplex

• 3.3V supply

• 5 mm x 5 mm QFN32 Package

• Standard Media Independent Interface (MII). Connects to any

CSMA/CD half−duplex capable MAC exposing the CRS and COL

pins

• Physical Layer Collision Avoidance (PLCA) through Local

Configuration for Collision−Free Operation on a Shared Medium

(Multi−Drop)

• Configuration and Monitoring using a standard MII Management

Interface (also known as MDIO)

• Partial configuration during boot sequence using pull resistors on

dedicated pins when the device is booting

• Enhanced Noise Immunity Mode, Allowing Communication at Noise

Levels Exceeding IEEE 802.3cg Specifications
