SN65HVDA195-Q1 汽车类 LIN、大多数 ECL 和 K-Line 物理接口
The SN65HVDA195 is the Local Interconnect Network (LIN) physical interface and MOST ECL interface, which integrates the serial transceiver with wake-up and protection features. The bus is a single-wire bidirectional bus typically used for low-speed in-vehicle networks using data rates to 20 kbps. The device can transmit with an effective data rate of 0 kbps since it does not have dominant state time out. The protocol output data stream on TXD is converted by the SN65HVDA195 into the bus signal through a current-limited wave-shaping driver as outlined by the LIN Physical Layer Specification Revision 2.0. The receiver converts the data stream from the bus and outputs the data stream via RXD. The bus has two states: dominant state (voltage near ground) and the recessive state (voltage near battery).
