6.3 Analog Part
The transmitter is a low-side driver with a pull-up resistor and slope control. The figure below shows
the characteristics of the transmitted signal, including the delay between internal TxD Signal and LIN
Signal. See Table 32: AC Parameters LIN Transmitter on page 55 and Table 33: AC Parameters LIN
Receiver on page 55 for timing values.
6.4 Slave operational range for proper self synchronization
The internal oscillator having a ± 10% accuracy over the voltage and temperature range, will
synchronize properly in the following conditions:
•
•
It is highly recommended to use the same type of reverse battery voltage protection diode for the
Master and the Slave nodes.
