Description

technical field [0001] The invention relates to the field of electronic information transmission, in particular to a data-free pin system. Background technique [0002] In order to reduce the number of connecting lines, a technology of transmitting digital signals through power lines has emerged in the field of power transmission. However, due to the high voltage intensity of power lines in power transmission scenarios, generally hundreds of volts or even thousands of volts, and The strength of the digital signal is very low, so when the digital signal is transmitted through the power line, it only needs to be processed simply, and it will not affect the power supply. However, in digital electronic systems, the strength of the power signal is very small, generally only a few volts. For example, the power supply of a mobile phone is up to 4.2 volts. The stability of the power supply voltage has a great influence. Therefore, most power line transmission systems cannot be use...

Therefore, most power line transmission systems cannot be used on low-voltage DC voltage, and a small part of the design that can be used for low-voltage DC voltage needs to use coils to obtain signals on the power line or load signals on the power line, which takes up a lot of space. Many, can not be integrated on the chip
