1 Introduction

The Fusion application board allows up to eight, high-speed, data sources, such as megapixel imagers and RADAR and LIDAR sensors, to be combined into two digital MIPI CSI-2 output ports, which are then connected to a Texas Instruments compatible evaluation module (EVM), with stand-alone operation (see Figure 1). Each sensor source connects to one of the hubs through a single coax cable or twisted pair (HSD). Two DS90UB960 FPD-Link III hubs are on the board. Each DS90UB960 device outputs four, high-speed, data inputs on only one CSI-2 LVDS interface. This greatly simplifies the system by combining eight sensor inputs into two outputs. These outputs are available on an external connector that attaches to an EVM or a similar SoC/processor. Because the Fusion application board supports multiple video inputs and multiplexing options, it is a well suited solution for Advanced Driver Assistance Systems (ADAS) development activity.

The Fusion application board EVM consists of the following:

PCB application board:
- Accepts eight, high-speed data inputs over FPD-Link III
- Uses two DS90UB960-Q1 devices for CSI-2 output to directly connect to CSI-2 video ports
- Provides a wide-range supply voltage for Power over Coax (PoC: 4 to 14 V)
FPD-Link III DS90UB960-Q1: Supports eight, high-speed, data inputs with only two outputs, for surround and stereoscopic view and ease of design
Interfaces with various TI EVMs, including TDA2Px, TDA2Ex, TDA3x, and TDA4
Stand-alone operation:
- Board power can come directly from a car battery (3.8 V to 65 V) or power source
- Onboard MSP430F2272-Q1 device for stand-alone operation
- Provides up to four 8 W and four 1.5 W PoC to each of the FPD-Link III inputs

Use this board with the Texas Instruments compatible EVM to enable a complete system solution.
