With the continuous development of technology, integrated circuits have been widely used in various fields. The TRS3238ECDBR chip is one of the most commonly used integrated circuits. It is an integrated module mainly used for optical drive digital optoelectronic conversion. This article mainly introduces the application field and working principle of TRS3238ECDBR.

Application Field

TRS3238ECDBR can be used for optical drive digital optoelectronic conversion in various fields. Generally, the TRS3238ECDBR chip can be used in devices such as sensors, converters, encoders, converters, digital optical interfaces and even USB and Ethernet interfaces. In addition, It is mainly used in many data communication fields, such as data communication interface cards, computers and their peripherals, communication equipment and its peripherals, navigation systems and instrumentation systems.

Working Principle

In the data communication between the TRS3238ECDBR chip and other parts, the transmitter uses high-speed digital signals as the input, and then uses the external resistor to adjust the driver to the target output current. At the same time, the RX receiving end is connected with the photoelectric conversion device to directly detect the optical signal output by the driver, then separate the encoded data from the high-speed signal, and finally, the data sent and received between the two is connected, then processed by the microprocessor, thereby realizing the transfer and storage of signals.

In the printed circuit board PCB design, in order to reduce the electromagnetic interference of the circuit, and to improve the reliability, the data output line of the TRS3238ECDBR chip needs to be designed independently, and connected with the ground near the TRS3238ECDBR chip. In addition, ground leads should be connected with the power source at two or more points after the two-meter buffer line to reduce interference and ensure data accuracy.

In summary, TRS3238ECDBR is mainly used for optical drive digital optoelectronic conversion and widely used in many data communication fields. Its working principle is to use external resistor to adjust the driver to the target output current and the RX receiving end to detect the optical signal. In the PCB design, sufficient ground line should be used to reduce electromagnetic interference and improve data accuracy.
