As I discussed in the lastinstallmentof this series, an RS-485 transceiver’s driver must be able to drive 1.5V across 32 unit loads and two 120Ω terminations. I didn’t mention it in the post, but the 120Ω value for termination resistors stems from what is known as the differential...
因此,MAX3471可以保持良好的信号质量,同时以64kbps的速度在125英尺的电缆上发送和接收,没有终端。图4显示了当100英尺的电缆和120欧姆termination电阻代替1000英尺的电缆和无终端电阻时,MAX3471电源电流的显著降低。 图4 电阻性终止表示功率的主要损失 RC终止 ...

One important aspect of RS485 communication is the termination of the transmission line. The termination resistors at both ends of the line help to match the impedance of the transmission line and minimize signal reflections. However, in a self-receiving circuit, we also need to include capacitors...
