TI中文支持网Part Number:DS90UB954-Q1Other Parts Discussed in Thread:TSER953
8.1.1 Power-over-Coax The TSER953 is designed to support the Power-over-Coax (PoC) method of powering remote sensor systems. With this method, the power is delivered over the same medium (a coaxial cable) used for high-speed digital video data, bidirectional control, and diagnostics data transmission. This method uses passive networks or filters that isolate the transmission line from the loading of the DC-DC regulator circuits and their connecting power traces on both sides of the link as shown in 图 8-1.
上面是datasheet上的一段话，大致意思是通过POC，电源可以通过用于高速数字视频数据、双向控制和诊断数据传输的同轴电缆传输。
那既然这样的话，TSER953及DS90UB954是否可以满足下面的需求：
摄像头一侧有一颗led驱动芯片和姿态传感器，这两个都支持iic通信；TSER953是否支持如下功能：比如主控想要控制led或者读取姿态传感器的数据，主控对DS90UB954下指令，然后DS90UB954通过poc传输控制信号，953解析后通过i2c与led驱动芯片和姿态传感器通信，然后再将得到的数据通过poc传回DS90UB954，954再通过i2c将数据传递给主控。

您好，
TSER953（V3Link）与DS90UB954（FPD-Link III）协议是不兼容的，无法一起使用。
