Product Overview
NCN5120: KNX Transceiver for Twisted Pair Networks
For complete documentation, see the data sheet
Product Description
The NCN5120 is the first IC from ON Semiconductor's family of KNX transceivers, handling the transmission and reception of data
on the bus. It integrates a 20 V regulator and two high efficient DC-DC converters generating a fixed 3.3 V and a selectable 3.3 to 21
V regulated voltage from the bus with 100 mA drive capability each. This transceiver is ideal for high power applications and has
been designed to reduce the bill of materials while supporting safe and reliable coupling to the bus thanks to features such as
selectable current slope, bus voltage and temperature monitoring.
Features
• KNX certified EIB transceiver with embedded PHY and MAC
layers (TP1-256)
• KNX communication speed of 9600 Bauds
• Two high efficient DC-DC converters generating board
supply:
- DC-DC1 : fixed 3.3 V
- DC-DC2 : adjustable between 3.3 and 21 V
• 20 V linear regulator
• Configurable fan-in model (up to 2 virtual nodes) and current
slopes
• Supervision of KNX bus voltage
• Control and monitoring of the DC-DC converters
• Configurable amount of repetition
• Buffering of sent data frames
• Optional auto acknowledge
Benefits
• High level of integration, minimal BOM cost
• Enables high power KNX applications to be connected and
supplied from the KNX bus
• While designed to offer unique features for most advanced
KNX systems, its flexiblity also simplifies integration into
legacy designs.
Applications
• In-home automation
• Building automation
End Products
• Smart lighting & switches
• Ventilation and air conditioning
• Thermostats
• Alarms and smoke detectors
