Chipanalog CA-IF1021S-Q1 Interface IC

Chipanalog CA-IF1021S-Q1

The CA-IF1021x-Q1 family of device is Local Interconnect Network (LIN) transceiver with integrated wake-up and protection features for automotive applications. LIN is low speed universal asynchronous receiver transmitter (UART) communication protocol used to support in-vehicle networks. The CA-IF1021x-Q1 transceiver controls the LIN bus state via the TXD input and reports the bus state on its open-drain output RXD between the protocol controller and physical LIN networks. These device features slew-rate control and wave-shaping to reach a very low level of electromagnetic emission (EME) within a broad frequency range.
