The SP238AET-L has fast and accurate signal transmission capability, and it also has strong anti-interference ability, which can ensure the stability of signal transmission. It can greatly reduce the effect of common mode signal on signal transmission, and protect the data line.

Working Principle

The SP238AET-L is a single chip package of optical isolator and receiver. The working principle of the SP238AET-L consists of the following parts:

Optical Isolator: The SP238AET-L consists of an optical isolator and two input and output amplifiers. The isolator is used to isolate two sections in different voltage levels, which can effectively prevent the two data lines from interfering with each other. The optical isolator isolates the device from the two output channels, which can effectively protect the device from high voltage or other external interference.

Input and Output Amplifiers: The SP238AET-L is equipped with two input and output amplifiers, one for optical signals, the other for electrical signals. The input amplifier amplifies the input signal, while the output amplifier amplifies the output signal. The input and output amplifiers ensure that the signal is correctly transmitted, and the signal transmission rate is fast.

Signal Processing Circuit: The signal processing circuit of the SP238AET-L can realize reliable signal transfer. It can filter out unwanted interference signals, reduce the noise generated by the signal, and make the received signal more accurate and stable. In addition, the signal processing circuit can also adjust the transmission speed according to the actual situation, and ensure that the signal transmission is accurate.

Conclusion

The SP238AET-L is an optical isolator and receiver with wide application fields and reliable performance. Its fast signal transmission rate and strong anti-interference ability make it an ideal choice for RS485, RS422 and other similar signal transmission systems. The working principle of the SP238AET-L consists of optical isolator, input and output amplifiers, and signal processing circuit, which play different roles in signal transmission.
