SIT1022Q is a dual channel Local Interconnect Network (LIN) physical layer transceiver that compliant with LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A, ISO 17987-4:2016 (12V) and SAE J2602 standards. It is mainly suitable for in-vehicle networks with a transmission rate of 1kbps to 20kbps. SIT1022Q controls the state of the LINx bus through the TXDx pin, and can convert the data stream sent by the protocol controller into a bus signal with the best slew rate and waveform shaping to minimize electromagnetic radiation emission (EME). The LIN bus output pin has an internal pull-up resistor. Only when used as a master node, the LIN bus port needs to be pulled up to VBAT through an external resistor in series with a diode.
