CoaXPress 简介
CoaXPress (简称CXP)是指一种采用同轴线缆进行互联的相机数据传输标准，主要用于替代之前的Camera Link协议，常见于科学相机、工业相机、医学图像、航空防务等场景。Camera Link 由于线缆的形式、传输速度等原因，已经不再适用于不断增长的数据带宽需求。
CXP是一个非对称的高速点对点串行传输协议，主要用于传输视频和静态图像，线缆多使用单条或多条同轴电缆。目前2.0标准的最高速度为单条lane 12.5Gbps，单条lane 上除了传输图像数据之外，还可以传输低速控制信号(41.6Mbps)、也可以利用该线缆对相机进行供电，即“Power-over-Coax”，单条线缆最长可达100m。
- 单条同轴线缆最高12.5Gbps的线速率，可以使用单条或者多条线缆，比如4条线缆可以最高提供50Gbps的数据速率
- 较长的线缆长度，比如3.125 Gbps 速率下线长可以到100m，12.5Gbps速率下可以到35m
- 数据传输具备实时和低延迟的特性，且延迟是固定的
- 精准实时的触发特性，支持通过同轴线缆发送触发，无需额外的通讯线缆
- 可以获得灵活可靠的性能，通过使用标准的同轴线缆，比如RG59 和 RG6规格，推荐使用RG6
- 易于集成的特性，图像、控制通讯、电源可以使用同一条线缆，且线缆价格便宜
CXP是一种点对点可扩展接口, 设备和HOST之间的物理介质为75Ω 同轴电缆。每一个CXP接口都包含1个MASTER连接和若干可选的扩展SLAVE连接，每一个连接都需要1条同轴线缆，通常设备会对这些连接进行编号，MASTER固定为0，SLAVE扩展接口依次递增。
图 1‑1 CXP链接结构
每一个connection都包含如下功能
- 高速串行数据(通常为Device到 Host downconnection), 最高 12.5 Gbps.
- 低速串行数据(通常为Host 到Device upconnection), 最高 41.6˙ Mbps .
- 供电功能Power (Host 到 Device), 最高13W.
CoaXPress 4R FMC

- HPC FMC连接器，使用FMC高密度连接器，符合VITA 57.1标准；
- Equalizer/Driver均衡器与驱动器，接收来自相机的高速downlink信号，发送来组FMC IO的低速控制信号；
- LED，每个通道配置1个双色LED，可以通过FMC IO实现R,G颜色任意组合；
- EEPROM，使用IIC接口的MT24C02 EEPROM，256Bytes容量，可以用于存储用户数据；
- 24V DC Power, 24V DC电源电路，可以接受来自FMC的12V或者来自外部电源的12V供电电源，为power on cable功能提供DC电源，理论CXP每通道提供最大13W输出功率；
- Power monitor，每路CoaXPress提供1路电流、电压监测电路，当电流超过门限后，会通过alert 端口向外发出警告；
- MicroBNC, 根据CoaXPress标准，子板使用MircroBNC连接器连接Device设备；
电源监测
使用4路PAC1720进行电源监测，4路IIC设备地址分别为0x48.0x49.0x5a,0x5b，分别对应channel 0-3。
图 2‑4 channel 0电源监测电路
PAC1720功能说明：
- PoE电流监测,通过SENSE1+和SENSE1-引脚两端的外部电阻（图中R44）上的电压间接得到(需结合FSR的设定)；
- PoE电压监测，通过SENSE2+引脚可以获取1/2的PoE电压，从而间接获取PoE电压；
- 过流提醒，用户可以编程限定PoE电压流过的电流，在过流时将ALERT信号拉低，从而触发电源控制系统；
- 通讯地址选择，用户可以通过改变ADDR_SEL引脚对地的电阻值来改变I2C的地址；
备注：具体功能参数设定，请参考PAC1720 datasheet。我们的范例程序会包含电源监测部分示例源代码供测试、参考。
