In the modern in-vehicle infotainment architectures such as Automotive Display and ADAS & Infotainment Fusion Controller, TXG1042-Q1 performs voltage-level translation across the board-to-board interface, allowing each PCB to operate from the native local I/O rail (for example, 3.3V on the host/SoC board and 1.8V on the peripheral board) as shown in Figure 3-5. This eliminates the need for a tracking supply to force match I/O voltages between the two PCBs. The rail management is simplified due to reduced power-tree coupling while maintaining reliable I/O compatibility across the connector.
