1.1 Ambarella介绍B6协处理器
Ambarella B6配套芯片支持高达4Kp30的多流视频捕获,用于高性能汽车应用,包括环绕视图、电子后视镜、ADAS和多通道视频录制。旨在支持复杂系统需要多个图像传感器部署在车辆、B6 co-proces-sors家族作为一种高效的数字信号处理器(DSP)之间的桥梁和四个图像传感器,允许360度覆盖没有引入延迟或视频质量的损失。此外,B6芯片使用简单的同轴电缆传输高分辨率Bayer RGB传感器数据。5x5mm b6家族由以下协处理器类型组成。
 
  1. B6FS:(远端)B6FS串行化芯片捕获拜耳RGB传感器输入,作为远程定位传感器和B6NS协处理器(或A9AQ芯片)之间的桥梁。
  2. B6NS:(近端)B6NS反序列化芯片结合1或2通道的视频流从B6FS,并通过MIpI-CSI或SlVS接口发送到一个Ambarella SoC。
  3. B6DFS:(远端)B6DFS芯片将从A9AQ接收到的SERDES数据以MIpI-DSI或Open lDI格式传输到远程外部显示器。如图1-3所示。
 
注:
※   B6FS串行化芯片捕获拜耳RGB传感器输入,作为远程传感器和B6NS芯片(需要将SERDES流转换为MIpI-CSI或SlVS流)或A9AQ芯片(使用A9AQ时不需要B6NS)之间的桥梁。
※   使用A9AQ输出一个或两个远程显示器时,需要B6DFS(远端)显示芯片。对于单个本地显示,不需要显示芯片。
※   同轴电缆(最高10m)可用于连接远程摄像机/显示器使用B6 SERDES解决方案。在多通道用例中,如果在系统处于活动状态时电缆断开,特定的通道将被丢弃;而其余的系统操作将不会中断。

1B6NS OVERVIEW
This datasheet for the B6NS automotive de-serializer chip from Ambarella begins with a brief introduc-tion to the B6 family of co-processors (Section 1.1) and a summary of the key features of the two-channel-capable  (Section 1.2).  Chapter 2 describes the B6NS modules and interfaces.  For pin details and electrical character-istics refer to Chapter 3 and Chapter 4, respectively.  See Chapter 5 for package information and Chapter 6 for Ambarella contact and ordering details.  
 
1.1 Introduction to B6 Co-Processors from Ambarella
Ambarella B6 companion chips enable multi-stream capture of up to 4Kp30 video for high-performance automo-tive applications including surround view, electronic mirrors, ADAS, and multi-channel video recording.  Designed to support complex systems requiring multiple image sensors deployed over a vehicle, the B6 family of co-proces-sors serves as a highly efficient bridge between the digital signal processor (DSP) and up to four image sensors, allowing 360-degree coverage without the introduction of latency or a loss of video quality.  Moreover, B6 chips 
enable high-resolution Bayer RGB sensor data to be transferred using a simple coaxial cable.  The 5x5-mm B6S 
family is composed of the following co-processor types.  
  1. B6FS: (Far-end) The B6FS serializer chip captures Bayer RGB sensor input, serving as a bridge between a remotely-located sensor and a B6NS co-processor (or an A9AQ chip).
  2. B6NS: (Near-end) The B6NS de-serializer chip combines the 1- or 2 channels of video stream from B6FS and sends it via MIpI-CSI or SlVS interface to an Ambarella SoC.
  3. B6DFS: (Far-End) The B6DFS chip transfers the SERDES data received from A9AQ in MIpI-DSI or Open lDI format to connect to remote external displays.  Refer to Figure 1-3 below.
 
Notes:
※  The B6FS serializer chip captures Bayer RGB sensor input, serving as a bridge between a remotely-located sensor and a B6NS chip (required to convert the SERDES stream into a MIpI-CSI or SlVS stream) or an A9AQ chip (B6NS is not required when using A9AQ).  
※  B6DFS (far-end) display chip is required when outputting to one or two remote display using A9AQ. For a single local display, no display chips are required.
※  Coaxial cables (up to 10m) can be used to connect remote cameras/ displays using the B6 SERDES solution.  In a multi-channel use case, if the cable is disconnected while the system is active, the specific channel will be dropped; while the rest of the system operation will not be disrupted.
