NCN5110 is areceiver−transmitter IC suitable for use in KNXtwisted pair networks (KNX TP1−256). NCN5110 is an bit (or PHY-only) transceiverwhich handles the transmission and reception of data on the bus. It generates from the unregulated bus voltage stabilized voltages for its own power needs as well as to power external devices. NCN5110 assures safe coupling to and decoupling from the bus and does not require external XTAL for proper operation.

• KNX certified TP transceiver with embedded PHY layer. 9600 Bauds communication speed.
• Two high efficient DC-DC converters + one linear regulator :
• - DC-DC1 : fixed 3.3 V
• - DC-DC2 : adjustable between 1.2 and 21 V
• - 20V linear regulator
• Bus Current Consumption up to 40 mA
• Supervision of temperature and of the power regulators
• Direct coupling of analog signaling to Host
• Extended ambient temperature range -40 to +105 degC
