The SN65HVDA100-Q1 device is a Local Interconnect Network (LIN) physical interface, which integrates the serial transceiver with wakeup and protection features. The LIN bus is a single-wire bidirectional bus typically used for low-speed in-vehicle networks using data rates from 2.4 kbps to 20 kbps. The LIN protocol output data stream on TXD is converted by the SN65HVDA100-Q1 into the LIN bus signal through a current-limited wave-shaping driver as outlined by the LIN Physical Layer Specification and ISO 17987. The receiver converts the data stream from the LIN bus and outputs the data stream through RXD. The LIN bus has two states: dominant state (voltage near ground) and recessive state (voltage near battery). In the recessive state, the LIN bus is pulled high by the internal pullup resistor (30 kΩ) and series diode, so no external pullup components are required for responder applications. Commander applications require an external pullup resistor (1 kΩ) plus a series diode per the LIN specification.

TIDA-00271 — 適用遠端攝影機和雷達模組的 ADAS 感測器互連參考設計基板
ADAS 感測器互連電路板適用於需要將攝影機、光達或雷達模組等遠端感測器連接至中央處理 ECU 的應用。電路板支援高達 3 個同軸和 1 個 LVDS 雙絞線資料輸入，以及 3 個 FMC 纜線和 1 個電路板至電路板連接器，以做為處理 ECU 的資料輸出。 透過同軸連接器（SMB 標準）連接的攝影機或其他感測器模組，直接透過互連板的同軸纜線（同軸電纜供電）供電。由於所有 IC 皆有獨立完整電源解決方案，且板載同軸纜線供電，因此單一汽車電池或類似寬電壓供應器可直接連接至 ADAS 感測器互連電路板上的電源接頭。板載 uC 和 LIN 介面可控制和配置互連電路板，以及隨插即用操作。
