Overview
The NCN5130MNTWG, produced by onsemi, is a receiver-transmitter IC designed for use in KNX twisted pair networks (KNX TP1-256). This IC integrates both the Physical (PHY) and Media Access Control (MAC) layers, enabling it to handle the transmission and reception of data on the bus. It generates stabilized voltages from the unregulated bus voltage to power both its own operations and external devices, such as microcontrollers and other components in a building network.
