Other 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TDES954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TDES954下指令,然后TDES954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TDES954,954再通过i2c将数据传递给主控。
